Answer 2

x=2 y=-9 over 7

Explanation:

-3x+7y=15 solving for x (add -7 to both sides)

-3x=-7y-15 (divide both sides by -3)

x=7 over 3y+5

substitue the x above for x in the equation -2x-7y=5

-2(7 over 3y+5)-7y=5

-35 over 3y-10+5

y= -9 over 7

substitue the y above in the equation x= 7 over 3y+5

x=2
