Solve the following simultaneous linear equations: x + y = 7xy 2x - 3y + xy = 0

Question

KnowledgeBoat · Accepted Answer

Given, x + y = 7xy 2x - 3y + xy = 0 First we note that x = 0, y = 0 is a solution of equations. Now when x ≠ 0 and y ≠ 0. Dividing x + y = 7xy by xy, Dividing 2x - 3y + xy = 0 by xy, Substituting as p and as q we get, q + p = 7 .......(iii) 2q - 3p = -1 ......(iv) Multiplying (iii) by 3 we get, 3q + 3p = 21 .......(v) Adding (iv) and (v) we get, ⇒ 2q - 3p + (3q + 3p) = -1 + 21 ⇒ 2q + 3q = 20 ⇒ 5q = 20 ⇒ q = ⇒ q = 4. . Substituting value of q in (iii) we get, ⇒ 4 + p = 7 ⇒ p = 3. . Hence, x = 0, y = 0 and x = .
