First, distribute the 9 to the variable and number within the parentheses.
9*x+9*8
Then, solve the two multiplication problems and add them to the overall equation.
9x+72-4=68
Combine like terms on the left.
9x+68=68
Subtract the 68 from the left as follows.
8x+68=68
-68 -68
8x=0
Divide by 8.
x=0/8
Simplify that to x=0.
Thus, x=0.
Hope this helps.
