You can put this solution on YOUR website!
You have two equations. we substitute y=5x-7 in the 2nd eq
\n" ); document.write( "-4x+y=-1( i believe this should be your eq. check your eq)
\n" ); document.write( "-4x+5x-7=-1
\n" ); document.write( "x-7=-1
\n" ); document.write( "x=6
\n" ); document.write( "
\n" );
