Solve the system of equations y= 3/2 - 1, -x+ y =-3

(x, y) = ( 1/2, -3 )

Step-by-step explanation:

y = -3

3/2 - 1 - x + y = - 3

3/2 - 1 - x - 3 = - 3

x = 1/2

solution : (x , y ) = ( 1/2, -3)  

here we are gonna see why is that answer :

-3 = 3/2 -1 - 1/2 - 3 = -3

-3 = -3 = -3

i hope this helps

be more specific
