13+x+10+4=10x
Add 5 and 8 to get 13.
23+x+4=10x
Add 13 and 10 to get 23.
27+x=10x
Add 23 and 4 to get 27.
27+x-10x=0
Subtract 10x from both sides.
27-9x=0
Combine x and -10x to get -9x.
-9x=-27
Subtract 27 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-27}{-9}
Divide both sides by -9.
x=3
Divide -27 by -9 to get 3.
