Question

solve each system using the elimination method.
x+3y=1
-x+5y=-9

Answer 1

x+3y=1
-x+5y=-9
----------
8y = -8
y = -1

Then plug -1 in the first equation.

x + 3(-1) = 1
x = 4

So the answer is y = -1, x = 4.

Answer 2

I can confirm, that ashrafh is in fact right.

Answer 3

@ashrafh
5x-2y=-6
4x+5y=-18
