Question
Solve the following equation : $\frac{3}{5} x +4=13$
✓
Answer
$\frac{3}{5} x +4=13$
$\Rightarrow \frac{3}{5} x +4-4$
$=13-4 ($ subtracting $4$ from both sides$)$
$\Rightarrow \frac{3}{5} x =9$
$\Rightarrow \frac{3}{5} x \times \frac{5}{3}$
$=9 \times \frac{5}{3} \ldots ($ Multiplying by $\frac{5}{3})$
$\therefore x =15$
$\Rightarrow \frac{3}{5} x +4-4$
$=13-4 ($ subtracting $4$ from both sides$)$
$\Rightarrow \frac{3}{5} x =9$
$\Rightarrow \frac{3}{5} x \times \frac{5}{3}$
$=9 \times \frac{5}{3} \ldots ($ Multiplying by $\frac{5}{3})$
$\therefore x =15$
