Solve the following system of equations by using the method of cross multiplication: 5/(x+1) - 2/(y-1) = 1/2, 10/(x+1) + 2(y-1) = 5/2

Substituting in , we get: ⇒ 5u - 2v = ⇒ 5u - 2v - = 0 ....(1) Substituting in , we get: ⇒ 10u + 2v = ⇒ 10u + 2v - = 0 ....(2) Multiply equation (1) and (2) by 2, we get, ⇒ = 0 ⇒ 10u - 4v - 1 = 0 .......(3) ⇒ = 0 ⇒ 20u + 4v - 5 = 0 .........(4) Applying cross-multiplication method for solving equations (3) and (4), we get : Now we have u = , Hence, x = 4, y = 5.
