DETAILED EXPLANATION

\n" ); document.write( "

Look at $\"105%2At=highlight_red%28+245+%29\"$ .
Moved these terms to the left $\"highlight_green%28+-245+%29\"$
It becomes $\"105%2At-highlight_green%28+245+%29=0\"$ .
\n" ); document.write( "

Look at $\"highlight_red%28+105%2At-245+%29=0\"$ .
Solved linear equation $\"highlight_red%28+105%2At-245=0+%29\"$ equivalent to 105*t-245 =0
It becomes $\"highlight_green%28+0+%29=0\"$ .
Result: $\"0=0\"$
