The first step for solving this equation is to distribute 
through the first set of parenthesis.
= (9x) × 
Remove the parenthesis.
= 9x ×
Reduce the numbers on the right side of the equals sign with 3.
= 3x
Now multiply both sides of the equation by 3.
x + 7 = 9x
Move the constant to the right side and then change its sign.
x = 9x - 7
Move the variable to the left side and change its sign.
x - 9x = -7
-8x = -7
Lastly,, divide both sides of the equation by -8 to find your final answer.
x =
