You can put this solution on YOUR website!
Solve using a system of linear equations.
\n" ); document.write( ".
\n" ); document.write( "4x +2y = 6
\n" ); document.write( "4x -5y = -1
\n" ); document.write( ".
\n" ); document.write( "subtract them
\n" ); document.write( ".
\n" ); document.write( "7y = 7
\n" ); document.write( "y = 1
\n" ); document.write( ".
\n" ); document.write( "substitute y=1 into the first equation
\n" ); document.write( ".
\n" ); document.write( "4x +2(1) = 6
\n" ); document.write( "4x = 4
\n" ); document.write( "x = 1
\n" ); document.write( ".
\n" ); document.write( "So it appears the solution is (1,1).
\n" ); document.write( ".
\n" ); document.write( "Graph the two equations it to check, but first you need to get them into y = mx+b form.
