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