Hello,
\n" ); document.write( "These 3x, 2x+2, and 5x-7 can be added as:
\n" ); document.write( " 3x + 2x+2 + 5x-7 =
\n" ); document.write( "Add like terms to get:
\n" ); document.write( "10x - 5
\n" ); document.write( "We can rewrite this as:
\n" ); document.write( "5(2x-1)
\n" ); document.write( "Make sense?
