Question

Solve each of the following equations and verify the answer in each case:
3x − 5 = 13

Answer 1

3x − 5 = 13
⇒ 3x − 5 + 5 = 13 + 5 [Adding 5 on both the sides]
⇒ 3x = 18
⇒ $\frac{3x}{3}=\frac{18}{3}$ [Dividing both the sides by 3]
⇒ x = 6
Verification:
Substituting x = 6 in the L.H.S.:
⇒ 3 $\times$ 6 − 5 = 18 − 5 = 13 = R.H.S.
L.H.S. = R.H.S.
Hence, verified.
