7x+y=-2
\n" ); document.write( "7x+3(y)=8 subtract.
\n" ); document.write( "------------
\n" ); document.write( "-2y=-10
\n" ); document.write( "y=-10/-2
\n" ); document.write( "y=5 ans.
\n" ); document.write( "7x+5=-2
\n" ); document.write( "7y=-2-5
\n" ); document.write( "x=-7
\n" ); document.write( "x=-1 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "7*-1+3*5=8
\n" ); document.write( "-7+15=8
\n" ); document.write( "8=8\r
