\n" ); document.write( " $\"A%2BB=180%5Eo\"$ --------------------> working eqn
\n" ); document.write( "but $\"A=3x%2B12\"$ ; $\"B=2x-22\"$
\n" ); document.write( "Subst. in working eqn
\n" ); document.write( " $\"3x%2B12%2B2x-22=180%5Eo\"$
\n" ); document.write( " $\"5x=180%5Eo%2B22-12\"$ , combine similar terms
\n" ); document.write( " $\"5x=190\"$ ----> $\"cross%285%29x%2Fcross%285%29=cross%28190%2938%2Fcross%285%29\"$
\n" ); document.write( " $\"x=38%5Eo\"$
\n" ); document.write( "So,
\n" ); document.write( " $\"A=3%2A38%2B12=114%2B12\"$
\n" ); document.write( " $\"highlight%28A=126%5Eo%29\"$
\n" ); document.write( " $\"B=2%2A38-22=76-22\"$
\n" ); document.write( " $\"highlight%28B=54%5Eo%29\"$
\n" ); document.write( "In doubt? go back working eqn,
\n" ); document.write( " $\"126%5Eo%2B54%5Eo=180%5Eo\"$
\n" ); document.write( " $\"180%5Eo=180%5Eo\"$
\n" ); document.write( "Thank you,
