Every thing looks good but for the blank I think they want the decimal representation of 1 / 3 which = .33333 Not sure though if that is what they are wanting. It is not very clear that is for sure.
Hello,
The 2 curves (lines) have the same value of y for:
y=4-x
y=2x+3
==>4-x=2x+3
==>3x=1
==>x=1/3
And y=4-1/3=11/3
Sol={(1/3,11/3)}
The answer is C.

You can do it as you have different triangles but with the same sides.
