Solving 2 Step Equations

It is important to learn this you can apply it to more difficult equations!
left side
We can only have one = sign in the equation.
= 12right side We also use INVERSE OPERATIONS.The inverse of multiplication is division. The inverse of division is multiplication. The inverse of subtraction is addition. The inverse of addition is subtraction. Use inverse operations to undo the constant before undoing the coefficient. Coefficient4x+9=21 ConstantExample 1 4x4x = 12 4 4 +x- 9 9==- 9 213solution divide both sides by 4 subtract 9 from both sides Example 2 2p - 3 = 272p = 302 p = 15+ 3 +3 2 add 3 to both sides solution divide both sides by 2 Your turn! 5y - 15 = 20Fill in the missing numbers. 5y = 35y =Solve these two step equations. 3y + 8 = 233y = 15y =Solve these two step equations. 4y - 1 = 154y = 16y =Solve these two step equations. 6y + 7 = 376y = 30y =Solve these two step equations. 8y - 2 = 148y =y =Solve these two step equations. 4y + 3 = 514y =y =Solve these two step equations. 5y - 1 = 295y =y =Solve these two step equations. 3y + 14 = 233y =y =Solve these two step equations. 8y - 11 = 218y =y =Solve these two step equations. 7y - 9 = 54y ==Solve these two step equations. 2y + 7 = 17y ==Solve these two step equations. 4y - 8 = 32y ==Solve these two step equations. 5y + 3 = 18y ==Solve these two step equations. 7y + 9 = 44y == |
