Question

Solve : 20/x + y + 3/x - y = 7  8/x - y - 15/x + y = 5

KnowledgeBoat · Accepted Answer

Given, equations : .......(1) .............(2) Multiplying equation (1) by 8, we get : Multiplying equation (2) by 3, we get : Subtracting equation (4) from (3), we get : Substituting value of x + y from equation 5 in equation 1, we get : Adding equation (5) and (6), we get : ⇒ (x + y) + (x - y) = 5 + 1 ⇒ 2x = 6 ⇒ x = ⇒ x = 3. Substituting value of x in equation (6), we get : ⇒ 3 - y = 1 ⇒ y = 3 - 1 = 2. Hence, x = 3 and y = 2.
