    4 + x/2 > 2x multiply both sides by 2 to get 4 + x > 4x bring x over 4> 4x - x 4 >3x 4/3 > x

    You multiplied both sides by 2 but still have 4 on the left side?

    @akb48, is it \[\frac{4 +x}{2} > 2x\] or \[4 + \frac{x}{2} > 2x\]

    multiply by 2 you get 8 + x > 4x subtracting x 8 > 3x dividing by 3 8/3 > x x < 8/3 \[x \in (-\infty, \frac{ 8 }{ 3 } )\]
