3m-2n=13........eq 1

\n" ); document.write( ":
\n" ); document.write( "add the equations together and the n terms will be eliminated because -2n+2n=-
\n" ); document.write( ":
\n" ); document.write( "we are left with 3m+m=13+7.

\n" ); document.write( ":
\n" ); document.write( "take m's found value and plug it into either equation and solve for n
