\frac{1}{3}x - x + 8 = \frac{1}{3}x - \frac{3}{3}x + 8 = 5 ] [ \frac{-2}{3}x + 8 = 5 ]
Subtract 8 from both sides: [ \frac{-2}{3}x = 5 - 8 ] [ \frac{-2}{3}x = -3 ]
Multiply both sides by -3 to get rid of the fraction: [ x = \frac{-3}{-2/3} ] [ x = \frac{-3}{-2} \cdot \frac{3}{1} ] [ x = \frac{9}{2} ]
Therefore, the solution to the equation is (x = \frac{9}{2}) or (x = 4.5).
