Step-by-step explanation:
Move all terms containing x to the left, all other terms to the right.
Add '9' to each side of the equation.
-9 + 9 + 7x = 75 + 9
Combine like terms: - 9 + 9 = 0
0 + 7x = 75 + 9
7x = 75 + 9
Combine like terms: 75 + 9 = 84
7x = 84
Divide each side by '7'.
x = 12
Simplifying
x = 12
