\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "____________________16 years ago__________Today_______8 years more
\n" ); document.write( "You__________________y-16_________________y_________y+8
\n" ); document.write( "Grandmother__________g-16=8(y-16)____________g_________g+8=3(y+8)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "First, solve the system \"highlight_green%28system%28g-16=8%28y-16%29%2Cg%2B8=3%28y%2B8%29%29%29\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Use that solution for g and y to evaluate y-8 and g-8.
