Answer:
A (-5,2)
Step-by-step explanation:
5x+y=-23
7x-3y=-41
3×(5x+y)=3×(-23)
15x+3y=-69
+7x-3y=-41
22x=-110
22. 22
x=-5
5x+y=-23
5(-5)+y=-23
-25+y=-23
+25. +25
y=2
When using elimination you add both equations together so that one variable cancels out the other. In this situation, y can be the variable. You must get the y-variables to cancel out leaving just the x- variables to solve for.
