Question

x-y=-4
x+3y=4

Answer 1

you want to find x and y?

Answer 2

x - y=-4
x + 3y=4

We can use elimination to solve for this (if that's what you want to do, you didn't specify). Since there are an equal number of x terms in both the equations, we can get started immediately by subtracting.

x - y=-4
x + 3y=4 subtract
-4y = -8
Dividing by -4.
y = 2

Plugging it back into one of our original equations (x - y = -4):
x - 2 = -4
Adding two.
x = -2

Solution: (-2, 2)

Answer 3

yes

Answer 4

oh well bluepig solved it:)

Answer 5

can you start eliminating the x first by subtracting x by x and getting zero ?
