Question #2: show my work

2x + 5y = 3
-2x - y = 5

x = -7/2, y=2

Step-by-step explanation:

2x + 5y = 3

-2x - y = 5

Add the two equations together to eliminate x

2x + 5y = 3

-2x - y = 5

     4y = 8

Divide each side by 4

4y/4 = 8/4

y =2

Now find x

2x +5y =3

2x +5(2) =3

2x+10 =3

Subtract 10

2x = -7

Divide by 2

2x/2 = -7/2

x = -7/2
