Answer 1

3x + 5y = -2

3x + 7y = 26

Subtract first equation from second

2y = 28

y = 14

Plug it in

x = -24

Answer 2

Answer:

Step-by-step explanation:

-3 x + 5 y = - 2  ...(1)

3 x + 7 y = 26....(2)

(1)+(2) : 12y =24

y=24/12=2

put this value in (1) or (2) : 3x +7(2) = 26

3x=26-14

3x = 12

x=12/3=4
