Answer:

x=2,y=3

Explanation:

First equation:
5x-7=y

Second equation:
-3x+12=2y

Put the first equation into the second one;


-3x+12=2(5x-7)

Expand;


-3x+12=10x-14

Group like terms;


12+14=10x+3x


26=13x

Divide both sides by 13


x=2

Put x=2 into the first equation;


5(2)-7=y


10-7=y


3=y

The solution is x=2,y=3
