2x-3y = 13
x + 2y = -4
For this case, the first thing we can do is rewrite the system of equations as:
2x-3y = 13
-2x-4y = 8
We now add both equations obtaining:
-7y = 21
We clear y:
y = 21 / -7
y = -3
We substitute the valos of y = -3 in any of the equations to find x:
x + 2 (-3) = - 4
We clear x:
x-6 = -4
x = -4 + 6
x = 2
Answer:
2x-3y = 13
x + 2y = -4
The solution to the system of equations is:
x = 2
y = -3
