36+9x=15x
Use the distributive property to multiply 9 by 4+x.
36+9x-15x=0
Subtract 15x from both sides.
36-6x=0
Combine 9x and -15x to get -6x.
-6x=-36
Subtract 36 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-36}{-6}
Divide both sides by -6.
x=6
Divide -36 by -6 to get 6.
