A pair of linear equations which has a unique solution x=2 y=-3 is(a)

1.	A pair of linear equations which has a unique solution x=2 y=-3 is(a) x+y =-1 and 2x-3y=-5 (b) 2x+5y=-11 and 4x-10y=-22 (c) 2x-y=1 and 3x+2y=0 (d) x-4y-14=0 and 5x-y-13=0
Answer» Answer: If x = 2, y = – 3 is a unique SOLUTION of any pair of equation, then these values must satisfy that pair of equations. From option (b), LHS = 2x + 5y = 2(2) + 5(- 3) = 4 – 15 = – 11 = RHS and LHS = 4X + 10y = 4(2) + 10(- 3)= 8 – 30 = – 22 = RHS hope this helps pls mark as the brainliest

Answer:

If x = 2, y = – 3 is a unique SOLUTION of any pair of equation, then these values must satisfy that pair of equations.

From option (b), LHS = 2x + 5y = 2(2) + 5(- 3) = 4 – 15 = – 11 = RHS

and LHS = 4X + 10y = 4(2) + 10(- 3)= 8 – 30 = – 22 = RHS

hope this helps
