Answer:

y=4,x=-3

Step-by-step explanation:

2x +3y=6...........1

x +2y=5...........2

multiply equation 1 by 1

multiply equation 2 by 2

2x+3y=6....×1

x+2y=5....×2

2x+3y=6.............3

2x+4y=10............4

subtract eqtn 3 from 4

4y-3y=10-6

:. y=4

put y=4 into eqtn 2

x+2y=5

x+2(4)=5

x+8=5

x=5-8

X=-3
