\"solve,then check algebraically and graphically.\"
\n" ); document.write( "The problem that is given to me is 7x+7=21.
\n" ); document.write( "----------------
\n" ); document.write( "7x+7 = 21
\n" ); document.write( "Subtract 7 from both sides to get:
\n" ); document.write( "7x = 14
\n" ); document.write( "Divide both sides by 7 to get:
\n" ); document.write( "x = 2
\n" ); document.write( "--------------------
\n" ); document.write( "Not sure what kind of graphing you are expected to do.
\n" ); document.write( "You could separately graph the left side of the equation
\n" ); document.write( "and the right side of the equation and see where they
\n" ); document.write( "meet:
\n" ); document.write( " $\"graph%28400%2C300%2C-10%2C10%2C-10%2C30%2C7x%2B7%2C21%29\"$
