1/3(b+12)-1/4(b+12)
\n" ); document.write( "Distribute,
\n" ); document.write( " $\"b%2F3%2B12%2F3-b%2F4-12%2F4=0\"$
\n" ); document.write( " $\"b%2F3%2Bcross%2812%294%2Fcross%283%291-b%2F4-cross%2812%293%2Fcross%284%291\"$
\n" ); document.write( " $\"%284b-3b%29%2F12%2B4-3=0\"$
\n" ); document.write( " $\"%28b%2F12%29%2B1=0\"$ , transpose
\n" ); document.write( " $\"b%2F12=-1\"$ , cross multiply
\n" ); document.write( " $\"b=-12\"$ -------------> final answer
\n" ); document.write( ".
\n" ); document.write( "Other way of solving it (as per your textbook):
\n" ); document.write( " $\"%281%2F3%29%28b%2B12%29-%281%2F4%29%28b%2B12%29\"$
\n" ); document.write( "Factor out $\"%28b%2B12%29\"$ :
\n" ); document.write( " $\"%28b%2B12%29%28%281%2F3%29-%281%2F4%29%29\"$
\n" ); document.write( " $\"%28b%2B12%29%28%284-3%29%2F12%29\"$
\n" ); document.write( " $\"%28b%2B12%29%281%2F12%29\"$
\n" ); document.write( " $\"highlight%28%28b%2B12%29%2F12%29%29\"$ ------------> same answer from textbook
\n" ); document.write( "If continue solving it, cross mutiply
\n" ); document.write( " $\"%28b%2B12%29=%2812%29%280%29\"$
\n" ); document.write( " $\"b%2B12=0\"$ , transpose and change sign,
\n" ); document.write( " $\"b=-12\"$ -----------------> same as answer on the 1st one above.
