Since the two equations equal y, set them equal to each other. 
x-1=-2x+5
From there, solve for x. 
First get x on one side, by using the addition property of equality. 
x-1=-2x+5
3x-1=5
Isolate x by adding 1. 
3x=6
Lastly get x all by itself by dividing each side by 3. 
x=2
You can now substitute your x-value, 2, into one of the equations (or both, if you wish; either one will result in the same answer.)
y=x-1
y=2-1
y=1
OR
y=-2x+5
y=-2(2)+5
y=-4+5
y=1
Final answer:
x=2 and y=1

Yes, they are.
If the triangles have three corresponding angles equal means that they are either similar or congruent.
The definition of congruent means that the sides have the same length. That is precisely what the statement says.
So, being the lengths of the corresponding angles the same the two triangles are identical, this is they are congruent.
