Answer:
x = 2
y = -8
Step-by-step explanation:
9x−2y=34 -------------------(I)
5x+2y=−6 -------------------(II)
Add equation (I) & (II) and so y will be eliminated and we could find the value of x.
(I) 9x - 2y = 34
(II) <u>5x + 2y = -6</u> {add}
14x = 28
x = 28/14
x = 2
Plug in x = 2 in equation (I)
9*2 - 2y = 34
18 - 2y = 34
-2y = 34 - 18
-2y = 16
y = 16/-2
y = -8
