Solve the following system of equations:
-2x + y = 1
4x + y = -1
1)(3, 1)
, 3)
, -3)
4)(1, 3)

We have two equation with two unknowns. Therefore, we can solve the x and y easily. There are a number of methods to apply here but I will be using substitution method. We do as follows:

-2x + y = 1
y = 1 + 2x

4x + y = -1
4x + 1 + 2x = -1
6x = -1 -1
6x = -2
x = -1/3

y= 1 + 2(-1/3)
y = 1/3

The answer is lol i dont know
