Question

Solve the system of linear equations by elimination.
9x−2y=34
5x+2y=−6

Answer 1

The answer is x=2 and y=-8

Answer 2

x = 2

y = -8

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) 5x + 2y = -6 {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
