Question
Solve the following equations. Check your result in case. $3x - 5 = 0$
✓

Answer

$3\text{x}-5=0$ Adding $5$ to both sides $3\text{x}-5+5=0+5$
$\Rightarrow3\text{x}=5$
$\Rightarrow\text{x}=\frac{5}{3}$ Check: $\text{L.H.S}=3\text{x}-5$
$=3\text{x}\frac{5}{3}-5$
$=5-5$
$=0$
$=\text{R.H.S}$ Hence $\text{ x}=\frac{5}{3}$
