You can put this solution on YOUR website!
Be careful! If w = -1, -2 + 4 = 2, not -6. Your second solution would have to be w = -5. Substituting \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

  • Graphical form: \"2w%2B4\" simplifies to \"-6\"
  • Text form: 2w+4 simplifies to -6
  • Cartoon (animation) form: \"simplify_cartoon%28+2w%2B4+%29\"
    For tutors: simplify_cartoon( 2w+4 )

DETAILED EXPLANATION

\n" ); document.write( "
Look at \"2%2Ahighlight_red%28+w+%29%2B4\".
Replaced w with -5
It becomes \"2%2Ahighlight_green%28+-5+%29%2B4\".
\n" ); document.write( "
Look at \"highlight_red%28+2%2A-5+%29%2Bhighlight_red%28+4+%29\".
Replace constants in expression: \"highlight_red%28+2%2A-5+%29\",\"highlight_red%28+4+%29\" with \"highlight_green%28+-6+%29\"
It becomes \"highlight_green%28+-6+%29\".
\n" ); document.write( "
Look at \"highlight_red%28+-6+%29\".
Removed extra sign in front of \"-6\"
It becomes \"-highlight_green%28+6+%29\".
Result: \"-6\"
