julia is 8 years older then dylan.
\n" ); document.write( "j = d + 8
\n" ); document.write( "sofia is four years younger than dylan.
\n" ); document.write( "s = d - 4
\n" ); document.write( " the sum of there ages is 55.
\n" ); document.write( "j + d + s = 55
\n" ); document.write( " what is each persons age?
\n" ); document.write( "replace j with (d+8), replace s with (d-4)
\n" ); document.write( "(d+8) + d + (d-4) = 55
\n" ); document.write( "combine like terms
\n" ); document.write( "3d + 4 = 55
\n" ); document.write( "3d = 55 - 4
\n" ); document.write( "3d = 51
\n" ); document.write( "d = 51/3
\n" ); document.write( "d = 17 yrs is Dylan's age
\n" ); document.write( ":
