Question

27) x=2 and y=-1 is the solution of the pair of lines is ___,write equation ​

Answer 1

Answer:

The given system of equations is

3x−2y=4 .(i)

2x+y=5 ..(ii)

Putting x=2 and y=1 in equation (i), we have

LHS =3×2−2×1=4=RHS

Putting x=2 and y=1 in equation (ii), we have

LHS=2×2+1×1=5=RHS

Thus, x=2 and y=1 satisfy both the equations of the given system.

Hence, x=2, y=1 is a solution of the given system.( please follow)

Answer 2

Answer:

pairs are same but we are get together are very less but we have single number
