Answer:
x = -57
Step-by-step explanation:
Simplify both sides of the equation:
Distribute:
(7)(x) + (7)(-9) = 8x + -6
7x + -63 = 8x -6
7x - 63 = 8x - 6
Subtract 8x from both sides
7x−63−8x=8x−6−8x
−x − 63 = −6
Add 63 to both sides
−x − 63 + 63 = −6 + 63
-x = 57
Divide both sides by -1
-x / -1 = 57 / -1
Therefore, you get x = -57
