Question
Solve the following equation and verify the answer: $3x - 5 = 13$
✓
Answer
$3x - 5 = 13$
$\Rightarrow 3x - 5 + 5 = 13 + 5$ [Adding $5$ on both the sides]
$\Rightarrow 3x = 18$
$\Rightarrow\frac{\text{3x}}{3}=\frac{18}{3}$ [Dividing both the sides by $3]$
$\Rightarrow x = 6$
Verification:
Substituting $x = 6$ in the $L.H.S.$
$\Rightarrow 3 \times 6 - 5 = 18 - 5 = 13 = R.H.S.$
$L.H.S. = R.H.S.$
Hence, verified.
$\Rightarrow 3x - 5 + 5 = 13 + 5$ [Adding $5$ on both the sides]
$\Rightarrow 3x = 18$
$\Rightarrow\frac{\text{3x}}{3}=\frac{18}{3}$ [Dividing both the sides by $3]$
$\Rightarrow x = 6$
Verification:
Substituting $x = 6$ in the $L.H.S.$
$\Rightarrow 3 \times 6 - 5 = 18 - 5 = 13 = R.H.S.$
$L.H.S. = R.H.S.$
Hence, verified.
