Answer:
(-5, 3)
Step-by-step explanation:
Elimination seems like the best method to use here.
x+y=-2
x-y=-8
---------
2x=-10
Divide everything by two
x=-5
Now plug it back into one of the original equations,
-5+y=-2
Add 5 to everything
y=3
Answer:
The solution is (-5, 3).
Step-by-step explanation:
If you have been told to solve this system of linear equations, start out by adding them together. The y terms then drop out, and we obtain:
2x = -10, implying that x = -5.
Selecting the first equation as our starting point in finding y:
-5 + y = -2.
We need to isolate y. To do this, add 5 to both sides:
y = -2 + 5, or y = 3.
Then the solution is (-5, 3).
