13. Solve for
x
by simplifying both sides of the equation, then isolating the variable.

There is no variable.
x  x = 0


I'm sorry that was probably confusing x= 13. A way to check would to be replacing x with 13 and solving the equation so 20(8+ 13)(131)= 39

try mathway.Com ms. She is wrong

20  (8+x)  ( x1) = 39
20  8  x  x + 1 = 39
132x = 39
and you can see that x = 13
