Rearranging Formulas

Hint 1: Get rid of the -2 on the right-hand sideRearrange the formula to make x the subject:to have x on its own. You can do it by adding2 to both sides of the formula or by moving-2 from right-hand side to left-hand side (Remember to change the - sign to +)y = x - 2 x = y + 2 y = x - 2 y + 2 = x +2 +2 We made x the subject Add 2 to both sides Swap sides Hint 1: Get rid of the -4 on the right-hand sideRearrange the formula to make x the subject:to have x on its own. You can do it by adding4 to both sides of the formula or by moving-4 from right-hand side to left-hand side (Remember to change the - sign to +)p = x - 4 x = p + 4 p = x - 4 p + 4 = x +4 +4 We made x the subject Add 4 to both sides Swap sides Hint 1: Get rid of the -3 on the right-hand sideRearrange the formula to make x the subject:to have x on its own. You can do it by adding3 to both sides of the formula or by moving-3 from right-hand side to left-hand side (Remember to change the - sign to +)2m = x - 3 2m + 3 = x x = 2m + 3 2m = x - 3 +3 +3 We made x the subject Add 3 to both sides Swap sides Hint 1: Get rid of the 2 on the right-hand sideRearrange the formula to make x the subject:to have x on its own. You can do it by taking2 away from both sides or by moving +2 from right-hand side to left-hand side (Remember to change the + sign to -)3t + 3 = x + 2 3t + 3 = x + 2 3t + 1 = x x = 3t + 1 -2 -2 We made x the subject Take away 2 from both sides Swap sides Hint 1: First we have to have the 3x and x term on one side of the formula. We can do it by taking x away from both sides or by moving the x term from righ-hand side to left-hand side. (Remember to change the + sign to -)Rearrange the formula to make x the subject:2x + 3y = x + 4 2x + 3y = x + 4 x + 3y = 4 x = 4 - 3y -x -3y -3y -x We made x the subject Take away 3y from both sides to make 2x on its own Take away xfrom both sides Hint 1: Because the x is multiplied by 3 here in order to make x the subject we have to divide both sides of the formula by 3. Rearrange the formula to make x the subject: y = 3x y/3 = x x = y/3 ÷3 y = 3x ÷3 Divide both sides by 3 We made x the subject Swap sides Hint 1: Because the x is multiplied by 5 here in order to make x the subject we have to divide both sides of the formula by 5.Rearrange the formula to make x the subject: m = 5x m/5 = x x = m/5 ÷5 m = 5x ÷5 Divide both sides by 5 We made x the subject Swap sides Hint 1: Because the x is multiplied by 3 here in order to make x the subject we have to divide both sides of the formula by 3. Rearrange the formula to make x the subject: 2p = 3x 2p/3 = x 2p = 3x x = 2p/3 ÷3 ÷3 Divide both sides by 3 We made x the subject Swap sides Hint 1: Because the x is multiplied by 5 here in order to make x the subject we have to divide both sides of the formula by 5.Rearrange the formula to make x the subject: 4y + 4 = 5x 4y + 4 = 5x x = 4y + 4 ÷5 5 4y + 4 5 = x ÷5 We made x the subject Divide both sides by 5 Swap sides Hint 1: Because the x is multiplied by 2p here in order to make x the subject we have to divide both sides of the formula by 2p.Rearrange the formula to make x the subject: n = 2px x = n/2p n/2p = x n = 2px ÷2p ÷2p Divide both sides by 2p We made x the subject Swap sides Hint 1: Get rid of the 3 on the right-hand sideRearrange the formula to make x the subject:to have 2x on its own. You can do it by taking3 away from both sides or by moving +3 from right-hand side to left-hand side (Remember to change the + sign to -)3p + 2 = 2x + 3 3p + 2 = 2x + 3 x = 3p - 1 = 2x 3p - 1 2 -3 3p - 1 2 = x -3 We made x the subject Divide both sides by 2 to get x on its own Swap sides Take away 3from both sides Hint 1: Get rid of the b on the right-hand sideRearrange the formula to make x the subject:to have x on its own. You can do it by takingb away from both sides of the formula or by moving the +b from right-hand side to left-hand side of the formula. (Remember to change the - sign to +)y = ax + b x = y - b = ax y - b y = ax + b -b a y - b a = x -b x is multiplied by a here, so we have to divide both sides by a We made x the subject Swap sides Take away b from both sides Hint 1: Notice that you can write this formula as:Rearrange the formula to make x the subject:y = 1/2 x y = x 2 2y = x x2 x = 2y y = x 2 x2 Multiply both sides by 2 We made x the subject Swap sides |
