DETAILED EXPLANATION

\n" ); document.write( "
Look at \"highlight_red%28+220%2At+%29%2Bhighlight_red%28+280%2At+%29=1550\".
Eliminated similar terms \"highlight_red%28+220%2At+%29\",\"highlight_red%28+280%2At+%29\" replacing them with \"highlight_green%28+%28220%2B280%29%2At+%29\"
It becomes \"highlight_green%28+%28220%2B280%29%2At+%29=1550\".
\n" ); document.write( "
Look at \"%28highlight_red%28+220+%29%2Bhighlight_red%28+280+%29%29%2At=1550\".
Added fractions or integers together
It becomes \"%28highlight_green%28+500+%29%29%2At=1550\".
\n" ); document.write( "
Look at \"highlight_red%28+%28highlight_red%28+500+%29%29%2At+%29=1550\".
Remove unneeded parentheses around factor \"highlight_red%28+500+%29\"
It becomes \"highlight_green%28+500+%29%2At=1550\".
\n" ); document.write( "
Look at \"500%2At=highlight_red%28+1550+%29\".
Moved these terms to the left \"highlight_green%28+-1550+%29\"
It becomes \"500%2At-highlight_green%28+1550+%29=0\".
\n" ); document.write( "
Look at \"highlight_red%28+500%2At-1550+%29=0\".
Solved linear equation \"highlight_red%28+500%2At-1550=0+%29\" equivalent to 500*t-1550 =0
It becomes \"highlight_green%28+0+%29=0\".
Result: \"0=0\"
