\n" ); document.write( "\n" ); document.write( "R + 2 = 2(H + 6 + 2) ___ R + 2 = 2H + 16 ___ substitute the equivalent value of R from the first equation to find H\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "then substitute the numerical value of H into the first equation to find R
