Solving One-Step Equations 2022

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. Example 1 The inverse of addition is subtraction, so we need to We need to UNDO the 9, which is added to + 9 = 12p p- 9 = - 9 3
Example 2 We need to UNDO the 3, which is subtracted from The inverse of subtraction is addition, so we need to add 3 to
- 3 = 17s + 3 = + 3
Example 3 The inverse of multiplication is division, so we need to divide We need to UNDO the 5, which is multiplied by = 35 5x 5
= 5
So what would we do here? x is being divided by 3. What is the inverse operation? • x 3 = 6 • x= fill in blanks--solve 3x=6 3x=6 x= fill in blanks--solve • x -5 = 8 • x= fill in blanks--solve -4x = 24 -4x=24 x= fill in blanks--solve • x -9 = -7 x= • fill in blanks--solve 7x = -56 7x = -56 x= fill in blanks--solve -7x = -35 -7x = -35 x= fill in blanks--solve • x -4 = 1 6 • x= |
