b for base length, x for either of the two equal sides.
\n" ); document.write( " $\"b=%281%2F3%29x\"$
\n" ); document.write( "-
\n" ); document.write( " $\"b%2B2x=105\"$ , the perimeter information.
\n" ); document.write( "Substitute for b, $\"%281%2F3%29x%2B2x=105\"$
\n" ); document.write( " $\"x%2B6x=315\"$
\n" ); document.write( " $\"7x=315\"$
\n" ); document.write( " $\"x=45\"$ --------- $\"b=%281%2F3%2945=15\"$ \n" ); document.write( "
