5x + 9 = 5 + 3x
On transposing 3x to L.H.S and 9 to R.H.S, we obtain
5x - 3x = 5 - 9
2x = -4
On dividing both sides by 2, we obtain
x = -2
L.H.S = 5x + 9 = 5 x (-2) + 9 = -10 + 9 = -1
R.H.S = 5 + 3x = 5 + 3 x (-2) = 5 - 6 = -1
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
