8x+128=40x
Use the distributive property to multiply 8 by x+16.
8x+128-40x=0
Subtract 40x from both sides.
-32x+128=0
Combine 8x and -40x to get -32x.
-32x=-128
Subtract 128 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-128}{-32}
Divide both sides by -32.
x=4
Divide -128 by -32 to get 4.
