\n" ); document.write( "let x = parents age; child = (x-18)
\n" ); document.write( " $\"x%2F%28%28x-18%29%29\"$ = $\"10%2F9\"$
\n" ); document.write( "10(x-18) = 9x
\n" ); document.write( "10x - 180 = 9x
\n" ); document.write( "10x - 9x = 180
\n" ); document.write( "x = 180 yrs age of parent, not likely \n" ); document.write( "
