Answer: (-5, 5)
Step-by-step explanation:
x + 5y = 20...(1)
2x - 7y = -45...(2)
Multiply equation 1 by -2 and add the equations
-2x - 10y = -40
+ 2x - 7y = -45
--------------------
- 17y =-85
-17y/-17 = -85/-17
y=5
Substitute y=5 into equation 1
x + 5y = 20
x + 5(5) = 20
x = 25-20
x=-5
Therefore the solutionto the system is (-5, 5)
