It is not clear from the question what is required to be done with the two linear equations. We can graph them and determine their point of intersection, as shown below

A D

C B

Line AB represents the graph of y= -x+3 and CD represents graph of y=x+1. For graphing the two lines, we can determine any two points on each. Plot these two points on the graph paper and join For y=-x+3 these can be (0,3) and (3,0).. Similarly, for y=x+1, two points can be (0,1) and (-1,0).

The point of intersection is (1,2).
