What is the solution (x, y) to the system of equations shown?
1 answer:
Answer:
x=-7, y=-5. (-7, -5).
Step-by-step explanation:
2y+x=-17
5x-4y=-15
---------------
x=-17-2y
5(-17-2y)-4y=-15
-85-10y-4y=-15
-85-14y=-15
14y=-85-(-15)
14y=-85+15
14y=-70
y=-70/14
y=-5
2(-5)+x=-17
-10+x=-17
x=-17-(-10)
x=-17+10
x=-7
