X+y=155. Y= -x+155
1.50x +4(-x+155)= 520
1.50x-4x+620=520
-2.5x =-100
X= 40. Y=110

Answer:
Y = 6 X=-1
Step-by-step explanation:
- Add the numbers 8x+-8x=0. 5y+y=6y. 22+14=36
- So that means 6y=36. So Y would equal 6
- Substitute the values it one of the original equations. 8x + 5(6) =22. 8x+30=22
- Minus 22 from both sides.
- That would give you 8x=-8
- So x would equal - 1
