Write an equation using x and y to represent the hanger.
If x is 6, what is y?
If x is 6, what is y?
Andre and Diego were each trying to solve 2x + 6 = 3x - 8. Describe the first step they each make to the equation.
The result of Andre’s first step was -x + 6 = -8
The result of Andre’s first step was -x + 6 = -8
The result of Diego’s first step was 6 = x - 8
The result of Diego’s first step was 6 = x - 8

-4(5x - 7) = -18 to 5x - 7 = 4.5 | arrow_right_alt | Add -4x to both sides |
-5x/4 = 4 to 5x = -16 | arrow_right_alt | Multiply both sides by -1/4 |
8 - 10x = 7 + 5x to 4 - 10x = 3 + 5x | arrow_right_alt | Add -4 to both sides |
6x + 9 = 4x -3 to 2x+9 = -3 | arrow_right_alt | Multiply both sides by -4 |
12x + 4 = 20x + 24 to 3x + 1 = 5x + 6 | arrow_right_alt | Multiply both sides by 1/4 |
