8x + 4 = 3(x - 1) + 7
8x + 4 = 3x - 3 + 7
Transposing 3x to L.H.S and 4 to R.H.S, we obtain
8x - 3x = - 3 + 7 - 4
5x = - 7 + 7
x = 0
L.H.S = 8x + 4 = 8 × (0) + 4 = 4
R.H.S = 3(x - 1) + 7 = 3 (0 - 1) + 7 = - 3 + 7 = 4
L.H.S. = R.H.S.
Hence, the result obtained above is correct.

Solve the inequations and graph their solutions on a number line – 4 ≤ 4x < 14, x ε N
Solve (\( \dfrac{x}{3}\)) + (\( \dfrac{1}{4}\)) < (\( \dfrac{x}{6}\)) + (\( \dfrac{1}{2}\)), x ε W. Also represent its solution on the number line.
If the replacement set is {-3, -2, -1, 0, 1, 2, 3}, solve the inequation \(\dfrac {(3x – 1) }{2} < 2\). Represent its solution on the number line.
Solve the inequations (\( \dfrac{3}{2}\)) – (\( \dfrac{x}{2}\)) > – 1, x ε N
