Answer:

X=+4

y=-2

Step-by-step explanation:

this is simultaneous equations

hence,

using elimination method

3x+2y=5

2x+2y=4

2y eliminates 2y

3x+2x=5x=5*4

5x=20

X=20/5

X=+4

(2)

to find "y"

take any of the equation above

using equ(2)

2x+2y=4

2(4)+2y=4

+2y=+4-8

+2y=-4

y=-4/2

y=-2

hope it useful!
