Question

Solve each of the following equations and verify the answer in each case:
$\frac{3x}{10}-4=14$

Answer 1

$\frac{3x}{10}-4=14$
or, $\frac{3x}{10}-4+4=14+4$ [Adding 4 on both the sides]
or, $\frac{3x}{10}=18$
or, $\frac{3x}{10}\times 10=18\times 10$ [Multiplying both the sides by 10]
or, $3x=180$
or, $\frac{3x}{3}=\frac{180}{3}$ [Dividing both the sides by 3]
or, x = 60
Verification:
Substituting x = 60 on both the sides:
$$\begin{gathered} \frac{3\times 60}{10}-4 \\ =\frac{180}{10}-4=18-4=14=R.H.S. \end{gathered}$$

L.H.S. = R.H.S.
Hence, verified.
