Solve the following pair of linear equations:

Answer»

3x - 5y = 4....... (1)9x - 2y = 7........(2)

Multiply eq(1) by 39x - 15y = 12......(3)

Subtract eq(2) from eq(3)-13y = 5y = - 5/13

Put value of y in eq(1), we get3x - 5*(-5/13) = 43x + 25/13 = 43x = 4 - 25/133x = (52 - 25)/133x = 27/13x = 9/13

Therefore, value of x = 9/13 and y = - 5/13
