Find the coordiaees of the vertices of a triangle, formed by the linear graphs of y=-x+1, 2x-y=2 and 2y=x+2

Answer 1

you should first try to find where the first two lines meet:
y=-x+1
2x-y=2

one way is replace the y in the second equation with (-x+1), like this:
2x - (-x+1)= 2
can you "solve for x" ?

Answer 2

would x = 1/4 ?

Answer 3

can you show your work?

2x - (-x+1)= 2
becomes
2x +x -1 = 2
now what ?
