Explanation:
Simplifying
8x + -9 = 8(x + -1)
Reorder the terms:
-9 + 8x = 8(x + -1)
Reorder the terms:
-9 + 8x = 8(-1 + x)
-9 + 8x = (-1 * 8 + x * 8)
-9 + 8x = (-8 + 8x)
Add '-8x' to each side of the equation.
-9 + 8x + -8x = -8 + 8x + -8x
Combine like terms: 8x + -8x = 0
-9 + 0 = -8 + 8x + -8x
-9 = -8 + 8x + -8x
Combine like terms: 8x + -8x = 0
-9 = -8 + 0
-9 = -8
Solving
-9 = -8
