Question

18x+6y=108
6x+10y=108

Answer 1

....what are u referring to?

Answer 2

x = 3

y = 9

Explanation:

18x+6y=108 ----------------(I)

6x+10y=108 -------------(II)

(I) 18x + 6y = 108

(II)*(-3) -18x - 30y = -324 {Now add, x will be eliminated}

- 24y = -216

y = -216/-24

y = 9

Substitute y = 9 in equation (I)

18x + 6*9 = 108

18x + 54 = 108

18x = 108 - 54

18x = 54

x = 54/18

x = 3
