7x-2x=50
\n" ); document.write( "5x=50
\n" ); document.write( "5x/5=50/5
\n" ); document.write( "x=10
\n" ); document.write( ".
\n" ); document.write( "Check by plugging (x=10) back into the original equation.
\n" ); document.write( "7x-2x=50
\n" ); document.write( "7(10)-2(10)=50
\n" ); document.write( "70-20=50
\n" ); document.write( "50=50 [checks out]
\n" ); document.write( "
