Question

Find a solution to the following system of equations.

2x + y = -2
-5x + 4y = 5

Answer 1

we can use the substitution method to solve this
first isolate the y in the first equation by subtracting 2x from both sides
you should get y = -2x - 2
then you can plug that into the second equation (-5x + 4y = 5)
which will get you -5x + 4(-2x-2) = 5
distribute and solve for x from there :)

once you get what x equals, plug that into y = -2x - 2 and solve for y

that should give you your solution ^_^
