3x+y=44
2x+y=31

The following will solve this set of system of equations:

Solved by pluggable solver: SOLVE linear system by SUBSTITUTION
Solve:
+system%28+%0D%0A++++3%5Cx+%2B+1%5Cy+=+44%2C%0D%0A++++2%5Cx+%2B+1%5Cy+=+31+%29%0D%0A++We'll use substitution. After moving 1*y to the right, we get:
3%2Ax+=+44+-+1%2Ay, or x+=+44%2F3+-+1%2Ay%2F3. Substitute that
into another equation:
2%2A%2844%2F3+-+1%2Ay%2F3%29+%2B+1%5Cy+=+31 and simplify: So, we know that y=5. Since x+=+44%2F3+-+1%2Ay%2F3, x=13.

Answer: system%28+x=13%2C+y=5+%29.



I hope the above steps were helpful. Good luck in your studies!
