Okay, lets convert these so that all of the variables are on one side of the equation:
y=-x%2B3--->y%2Bx=3
y=x%2B1--->-1=x-y
Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++1%5Cx+%2B+1%5Cy+=+3%2C%0D%0A++++1%5Cx+%2B+-1%5Cy+=+-1+%29%0D%0A++We'll use substitution. After moving 1*y to the right, we get:
1%2Ax+=+3+-+1%2Ay, or x+=+3%2F1+-+1%2Ay%2F1. Substitute that
into another equation:
1%2A%283%2F1+-+1%2Ay%2F1%29+%2B+-1%5Cy+=+-1 and simplify: So, we know that y=2. Since x+=+3%2F1+-+1%2Ay%2F1, x=1.

Answer: system%28+x=1%2C+y=2+%29.
