Answer:

12

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
