A pair of linear
If x = 2 and y = - 3 is a unique solution of any pair of equation, then these values must satisfy that pair of equations.
Putting the values in the equations for every option and checking it -
From option (b).
LHS = 2x + 5y = 2(2+(- 3) = 4 + (- 15) = - 11 = RHS
LHS = 4x + 10y = 4(2) +10(- 3) = 8 + (- 30) = - 22 = RHS
It satisfies the pair of linear equation and hence is the unique solution for the equation.
