answer?

According to your equation:   2y = -5   so    y = -2.5

ALSO:     x + 2x - 3y = -5

               3x - 3(-2.5) = -5

               3x + 7.5      = -5

                3 x = -12.5

                   x = - 125/30 =  - 4 1/6

IF you entered your Q correctly !

If your equations are:

 

2y = x + 2               (1)

x - 3y = -5              (2)

 

Then:

 

Rearrange (2) to get:   x = -5 + 3y     (3)

 

Replace x in (1) using (3):   2y = -5 + 3y + 2  

Rearrange: -y = -3  so   y = 3

 

Put this into (3):    x = -5 +3*3   so  x = 4

 

(x, y) = (4, 3)
