Question
Solve: $\frac{2 x}{3}+\frac{x}{2}-\frac{3 x}{4}=1$
✓
Answer
$\begin{aligned} & \frac{2 x}{3}+\frac{x}{2}-\frac{3 x}{4}=1 \\ & \Rightarrow \frac{8 x+6 x-9 x}{12}=1 \\ & \Rightarrow 8 x+6 x-9 x=12 \times 1 \\ & \Rightarrow 8 x+6 x-9 x=12 \\ & \Rightarrow 14 x-9 x=12 \\ & \Rightarrow 5 x=12 \\ & \Rightarrow x=\frac{12}{5}=2 \frac{2}{5}\end{aligned}$
