You can put this solution on YOUR website!
Hint:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Solve the second equation for y\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x-y=7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-y = -2x+7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = 2x-7\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then plug this into the first equation\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x-3y=6 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x-3(2x-7) = 6 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "2x-6x+21 = 6 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-4x+21 = 6 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I'll let you finish. Solve for x. Then use the solution for x to find the solution for y.
\n" ); document.write( " \n" ); document.write( "
