Question 1185077

. Timothy is seven years younger than Mathew. Write the names from smallest to the big one

let Joseph’s age be {{{J}}}, Timothy’s age be {{{T}}}, and Mathew’s age be {{{M}}}


if Joseph is five years older than Timothy, then Timothy is five years younger so we have

 {{{T=J-5}}}..eq.1

if Timothy is seven years younger than Mathew, we have

{{{T=M-7}}}...eq.2 ->Timothy is {{{7}}} years younger  than Mathew

=>{{{J-5=M-7}}}
{{{J-5+7=M}}}
{{{M=J+2}}} ->Joseph is {{{2}}} year younger than Mathew

=>the names from smallest to the big one:
Timothy, Joseph, Mathew
