Question

Solve the following equation and verify the answer:

6x + 5 = 2x + 17

Answer 1

6x + 5 = 2x + 17
⇒ 6x  − 2x = 17 − 5 [Transposing 2x to the L.H.S. and 5 to the R.H.S.]
⇒ 4x = 12
⇒ `(4x)/4=12/4` [Dividing both the sides by 4]
⇒ x = 3
Verification:
Substituting x = 3 on both the sides:
L.H.S.: 6(3) + 5
= 18 + 5
= 23
R.H.S.: 2(3) + 17
= 6 + 17
= 23
L.H.S. = R.H.S.
Hence, verified.
