let x be Jill's age and m be Mike's age
\n" ); document.write( ":
\n" ); document.write( "1) m = 3x -2
\n" ); document.write( ":
\n" ); document.write( "2) m + x = 38
\n" ); document.write( ":
\n" ); document.write( "using equation 1, substitute for m in equation 2
\n" ); document.write( ":
\n" ); document.write( "3x -2 +x = 38
\n" ); document.write( ":
