Answer
$\displaystyle \frac{3}{4}$
Work Step by Step
The aim is, step by step, to isolate x on one side of the equation.
Add 3x to both sides and the right side will have no x's
Subtract 2 from both sides and the left side will contain only x's.
$5x+2=8-3x\qquad ... /+3x-2$
$ 5x+3x=8-2\qquad$... simplify
$8x=6\qquad $divide both sides by 8 to isolate x
$ 8x=6\qquad$ .../$\div$8
$x=\displaystyle \frac{6}{8}=\frac{3}{4}$
Solution: $\displaystyle \frac{3}{4}$
