200+40x=90x
Use the distributive property to multiply 40 by 5+x.
200+40x-90x=0
Subtract 90x from both sides.
200-50x=0
Combine 40x and -90x to get -50x.
-50x=-200
Subtract 200 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-200}{-50}
Divide both sides by -50.
x=4
Divide -200 by -50 to get 4.
