The perimeter of rectangular poster is 80 inch. The length is 10 inches greater than the width. Find the length.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 1. The perimeter P means adding up all the four 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+10 be the length since the length is 10 inches greater than the width\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 4. Then, P=w+w+w+10+w+10=80.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 5. Solving yields the following steps\r

DETAILED EXPLANATION

\n" ); document.write( "
Look at \"w%2Bw%2Bw%2Bhighlight_red%28+10+%29%2Bw%2Bhighlight_red%28+10+%29=80\".
Added fractions or integers together
It becomes \"w%2Bw%2Bw%2Bhighlight_green%28+20+%29%2Bw=80\".
\n" ); document.write( "
Look at \"w%2Bw%2Bw%2Bhighlight_red%28+20+%29%2Bw=80\".
Moved \"20\" to the right of expression
It becomes \"w%2Bw%2Bw%2Bw%2Bhighlight_green%28+20+%29=80\".
\n" ); document.write( "
Look at .
Eliminated similar terms \"highlight_red%28+w+%29\",\"highlight_red%28+w+%29\",\"highlight_red%28+w+%29\",\"highlight_red%28+w+%29\" replacing them with \"highlight_green%28+%281%2B1%2B1%2B1%29%2Aw+%29\"
It becomes \"highlight_green%28+%281%2B1%2B1%2B1%29%2Aw+%29%2B20=80\".
\n" ); document.write( "
Look at .
Added fractions or integers together
It becomes \"%28highlight_green%28+4+%29%29%2Aw%2B20=80\".
\n" ); document.write( "
Look at \"highlight_red%28+%28highlight_red%28+4+%29%29%2Aw+%29%2B20=80\".
Remove unneeded parentheses around factor \"highlight_red%28+4+%29\"
It becomes \"highlight_green%28+4+%29%2Aw%2B20=80\".
\n" ); document.write( "
Look at \"4%2Aw%2B20=highlight_red%28+80+%29\".
Moved these terms to the left \"highlight_green%28+-80+%29\"
It becomes \"4%2Aw%2B20-highlight_green%28+80+%29=0\".
\n" ); document.write( "
Look at \"4%2Aw%2Bhighlight_red%28+20+%29-highlight_red%28+80+%29=0\".
Added fractions or integers together
It becomes \"4%2Aw%2Bhighlight_green%28+-60+%29=0\".
\n" ); document.write( "
Look at \"4%2Aw%2Bhighlight_red%28+-60+%29=0\".
Removed extra sign in front of \"-60\"
It becomes \"4%2Aw-highlight_green%28+60+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+4%2Aw-60+%29=0\".
Solved linear equation \"highlight_red%28+4%2Aw-60=0+%29\" equivalent to 4*w-60 =0
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
