50 POINTS!!!Solve by the linear combination method. 2x + 8y = –2 5x + 6y = 9(3, –1)(–2, 2)(–2, 7)(–1, 3)

2x + 8y = –2 --------- (1)
5x + 6y = 9   --------- (2)

(1) x 5 : 10x + 40y = -10 ----------- (1a)
(2) x 2 : 10x + 12y = 18  ----------- (2a)

(1a) - (2a) :    28y = -28
                         y = -1

Substitute y = -1 into (1)
2x + 8(-1) = –2
2x - 8 = -2
2x = 6
x = 3

Answer : (3, -1) (Answer A)
