-6x = 9x + 36 how to check
how to check a fraction answer.

-6x = 9x + 36
-6x - 9x = 9x + 36 - 9x
-15x = 36
-15x / -15 = 36 / -15
x = -12/5

You check it the same way you check any answer.
Plug the value of x into the equation, everywhere
an x appears. Then, solve the equation.

-6x = 9x + 36
-6(-12/5) = 9(-12/5) + 36
72/5 = -108/5 + 36
72/5 = -108/5 + 180/5
72/5 = (-108 + 180)/5
72/5 = 72/5
