Answer:
x=4, y=10
Step-by-step explanation:
−5y+8x=−18
5y+2x=58
Add the two equations together to eliminate y
−5y+8x=−18
5y+2x=58
-------------------
10x = 40
Divide by 10
10x/10 = 40/10
x = 4
Now we need to find y
5y +2(4) = 58
5y+8 = 58
Subtract 8 from each side
5y+8-8 = 58-8
5y = 50
Divide by 5
5y/5= 50/5
y= 10
