The length of a rectangle is 3 in. more than its width. The perimeter of the rectangle is 30 in.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 1. Perimeter P means adding up all 4 sides of a rectangle.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 2. Let w be the width.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 3. Let w+3 be the length.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 4. Then, P=w+w+w+3+w+3=4w+6=30\r

This is an equation! Solutions: w=6.
Graphical form: Equation $\"4w%2B6=30\"$ was fully solved.
Text form: 4w+6=30 simplifies to 0=0
Cartoon (animation) form: $\"simplify_cartoon%28+4w%2B6=30+%29\"$
For tutors: simplify_cartoon( 4w+6=30 )

DETAILED EXPLANATION

\n" ); document.write( "

Look at $\"4%2Aw%2B6=highlight_red%28+30+%29\"$ .
Moved these terms to the left $\"highlight_green%28+-30+%29\"$
It becomes $\"4%2Aw%2B6-highlight_green%28+30+%29=0\"$ .
\n" ); document.write( "

Look at $\"4%2Aw%2Bhighlight_red%28+6+%29-highlight_red%28+30+%29=0\"$ .
Added fractions or integers together
It becomes $\"4%2Aw%2Bhighlight_green%28+-24+%29=0\"$ .
\n" ); document.write( "

Look at $\"4%2Aw%2Bhighlight_red%28+-24+%29=0\"$ .
Removed extra sign in front of $\"-24\"$
It becomes $\"4%2Aw-highlight_green%28+24+%29=0\"$ .
\n" ); document.write( "

Look at $\"highlight_red%28+4%2Aw-24+%29=0\"$ .
Solved linear equation $\"highlight_red%28+4%2Aw-24=0+%29\"$ equivalent to 4*w-24 =0
It becomes $\"highlight_green%28+0+%29=0\"$ .
Result: $\"0=0\"$
