Solve : and . Hence, find 'm' for which y = mx - 4.

Lets take = u and = v. The given equation becomes, 2u + v = ⇒ 12u + 4v = 1 And, 3u + 2v = 0 Multiply second equation by 4 and subtract from first equation, we get (3u + 2v = 0) x 4 ⇒ v = - Substituting the value of v in equation (2), we get: ⇒ 3u + 2 = 0 ⇒ 3u - = 0 ⇒ 3u = ⇒ u = So, x = = 6 and y = = -4 Substituting the value of x and y in y = mx - 4, we get: ⇒ -4 = m 6 - 4 ⇒ -4 + 4 = 6m ⇒ 0 = 6m ⇒ m = ⇒ m = 0 Hence, the value of x = 6 , y = -4 and m = 0.
