Question
Solve: $\frac{\text{2x}}{5}-\frac{\text{x}}{2}=\frac{5}{2}$
✓
Answer
$\frac{\text{2x}}{5}-\frac{\text{x}}{2}=\frac{5}{2}$ Or,
$\frac{\text{4x-5x}}{10}=\frac{5}{2}$ [Taking $L.C.M.$ as $10]$
$\Rightarrow\frac{\text{x}}{10}=\frac{5}{2}$
$\Rightarrow\frac{\text{x}}{10}\times(-10)=\frac{5}{2}\times(-10)$ [Multiplying both the sides by $(-10)] \text{x}=-25$
$\frac{\text{4x-5x}}{10}=\frac{5}{2}$ [Taking $L.C.M.$ as $10]$
$\Rightarrow\frac{\text{x}}{10}=\frac{5}{2}$
$\Rightarrow\frac{\text{x}}{10}\times(-10)=\frac{5}{2}\times(-10)$ [Multiplying both the sides by $(-10)] \text{x}=-25$
