\frac{86}{2}=x+5+3x
Divide both sides by 2.
43=x+5+3x
Divide 86 by 2 to get 43.
43=4x+5
Combine x and 3x to get 4x.
4x+5=43
Swap sides so that all variable terms are on the left hand side.
4x=43-5
Subtract 5 from both sides.
4x=38
Subtract 5 from 43 to get 38.
x=\frac{38}{4}
Divide both sides by 4.
x=\frac{19}{2}
Reduce the fraction \frac{38}{4} to lowest terms by extracting and canceling out 2.
