Solve the liner equation $$\frac{n}{2} - \frac{3n}{4} + \frac{5n}{6} = 21$$

Asked by Aaryan | 1 year ago |  95

##### Solution :-

$$\frac{n}{2} - \frac{3n}{4} + \frac{5n}{6} = 21$$

L.C.M. of the denominators, 2, 4, and 6, is 12.

Multiplying both sides by 12, we obtain

6n - 9n + 10n = 252

⇒ 7n = 252

⇒ n = $$\frac{252}{7}$$

⇒ n = 36
