You can put this solution on YOUR website!
well you got started right but it is also true that K+J=101
\n" ); document.write( ":where Kaylee's and Justin's age are K and J respectively
\n" ); document.write( ":
\n" ); document.write( "K=J+55....eq 1
\n" ); document.write( "K+J=101...eq 2
\n" ); document.write( ":
\n" ); document.write( "we have 2 equations with 2 unknowns
\n" ); document.write( ":
\n" ); document.write( "take K's value in eq 1 and plug it into eq 2
\n" ); document.write( ":
\n" ); document.write( "J+55+J=101
\n" ); document.write( ":
\n" ); document.write( "2J=46
\n" ); document.write( ":
\n" ); document.write( " $\"highlight%28J=23%29\"$ Justin's age
\n" ); document.write( ":
\n" ); document.write( " $\"highlight%28K=J%2B55=23%2B55=78%29\"$ Kaylee's age
