\n" ); document.write( "Then we can write
\n" ); document.write( "2(x + 15) = 6x
\n" ); document.write( "Solve for x:
\n" ); document.write( "2x + 30 = 6x
\n" ); document.write( "4x = 30
\n" ); document.write( "x = 7.5
\n" ); document.write( "Check:
\n" ); document.write( "2(7.5+15) = 45
\n" ); document.write( "6*7.5 = 45
