Step-by-step explanation:
Simplifying
9(x + -3) = 45
Reorder the terms:
9(-3 + x) = 45
(-3 * 9 + x * 9) = 45
(-27 + 9x) = 45
Solving
-27 + 9x = 45
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '27' to each side of the equation.
-27 + 27 + 9x = 45 + 27
Combine like terms: -27 + 27 = 0
0 + 9x = 45 + 27
9x = 45 + 27
Combine like terms: 45 + 27 = 72
9x = 72
Divide each side by '9'.
x = 8
Simplifying
x = 8
