Wow, age 54?\r

\n" ); document.write( "\n" ); document.write( "1. \"A=%281%2F2%29bh\"
\n" ); document.write( "To solve for b, you need to isolate it
\n" ); document.write( "First step, get rid of \"1%2F2\" by multiplying both sides by 2
\n" ); document.write( "\"2A=bh\"
\n" ); document.write( "To get b alone, divide both sides by h
\n" ); document.write( "\"highlight%28%282A%29%2Fh=b%29\" :)\r

DETAILED EXPLANATION

\n" ); document.write( "
Look at \"%28-highlight_red%28+177+%29-highlight_red%28+26+%29%29%2F-13\".
Added fractions or integers together
It becomes \"%28highlight_green%28+-203+%29%29%2F-13\".
\n" ); document.write( "
Look at \"%28highlight_red%28+-203+%29%29%2F-13\".
Removed extra sign in front of \"-203\"
It becomes \"%28-highlight_green%28+203+%29%29%2F-13\".
\n" ); document.write( "
Look at \"highlight_red%28+%28-highlight_red%28+203+%29%29%2F-13+%29\".
Remove unneeded parentheses around factor \"highlight_red%28+203+%29\"
It becomes \"-highlight_green%28+203+%29%2F-13\".
\n" ); document.write( "
Look at \"-highlight_red%28+203%2F-13+%29\".
Removed extra sign in front of \"15.6153846153846\"
It becomes \"highlight_green%28+15.6153846153846+%29\".
Result: \"15.6153846153846\"
