systems of inqualities?

Question

x+y=2

y=-2

y-x=2

show working please

Answer 1

I only see equalities... and what are you supposed to do with them?

Assuming you need to graph them, first put them in terms of y:
1) y = -x + 2
This has a slope of -1 (diagonal downward) and a y-intercept of 2.

2) y = -2
This has no slope (horizontal line) and goes through the y-intercept of -2.

3) y = x + 2
This has a slope of 1 (diagonal upward) and a y-intercept of 2.

The lines are shown in the attached diagram... Now what do you want to do with them?

Answer 2

where are the inequalities?
