You can put this solution on YOUR website!
x+%2B+6y+=+32 ---------> eqn 1
-x+%2B+3y+=+13 --------> eqn 2
9y=45system%28cross%28x%29%2B6y=32%2Ccross%28-x%29%2B3y=13%29, cancel out x since "+" & "-".
continuing:
cross%289%29y%2Fcross%289%29=cross%2845%295%2Fcross%289%29
y=5
For x, go back eqn 1:
x%2B6%285%29=32
x=32-30
x=2
(x,y) --------> (2,5), FINAL ANSWER
In doubt? go back eqn 2 this time:
-2%2B3%285%29=13
-2%2B15=13
13=13
Thank you,
