Answer»

2x-5y=4.........equation(1)3x-8y=5..............equation(2)

Equation(1)

2x-5y=42x=4+5y

x=(4+5y)/2............equation(A)

Equation(2)3x-8y=5.........equa.(2)

Put value of (A) in (2)

3[(4+5y)/2]-8y=5(12+15y)/2-8y=5(12+15y-16y)/2=5..........(BY TAKING LCM)12-y=5×212-y=10y=12-10y=2Equation(1)2x-5y=4

Put value of y in any equation.

2x-5y=42x-5×2=42x-10=42x=4+102x=14x=14/2x=7
