Let

Taking x terms and constants on both sides we get,

Solve eq (1) and (2) for A and B.

Multiply eq (1) by 2 and write the equations in column form, then subtract them, to find the value of A.

The resultant equation is .

Substitute the value A = 5 in either of the equations (1) and (2), to find the value of B.

Equation (1) : A + B = 1

5 + B = 1

B = 1 - 5 = - 4.

Therefore,
