Question
Verify by substitution that: $x = 4$ is the root of $\frac{3\text{x}}{2}=6$

Answer

$x = 4$ is the root of $\frac{\text{3x}}{2}=6$
 Now, substituting $x = 4$ in place of $‘x’$ in the given equation:
$\frac{\text{3x}{}}{2}=6,$ $\frac{3\times4}{2}=6$ $\frac{12}{2}=6$ $6=6$
Since, $L.H.S. = R.H.S.$
Hence, $x = 4$ is the root of $\frac{3\text{x}}{2}=6$
