Question

(D) x + y = 1 3 3x - y - 13 = 0
A pair of linear equations which has a unique solution r=2 and y=-35
(A) x + y = 1 and 2x - 3y = -5
(B) 2r + 5y = -11 and 3x - 2y = 12
(C) 2x + 5y = -11 and 4x - 10y = -13
(D) x + y = 1 and 5x - y - 13 = 0​

Answer 1

x=-2÷5 y=7÷5 answer to (A)
r=2. y=-3 answer to (B)
