Answer:
x=4 y=5
Step-by-step explanation:
8x-9y=-13
2x-3y=-7
Solve for y:
Multiply the bottom by 4 to have the x's equal each other and cancel out:
8x-9y=-13
8x-12y=-28
Then subtract:
0x+3y=15
y=15/3 -> y=5
Solve for x:
Multiply the bottom by 3 to have the y's equal each other and cancel out:
8x-9y=-13
6x-9y=-21
Then subtract:
2x=8
x=4
