Question

y=6-x and y=x-2

a (2,4)
b (-4,2)
c (4,2)
d no solution

Answer 1

y=6-x rearrange this equation to look like
-6=-x-y

Plug the second equation into the first equation to look like this
-6=-x-(x-2) Simplify to look like this
-6=-2x + 2
-6-2=-2x
-8=-2x
4=x

Plug in x=4 into the second equation and you get this

y= 4-2
y=2

So your answer is c
