Question 1175131

let Ricardo  ‘s age be {{{R}}} and Hillary's age {{{H}}}



if Ricardo is {{{6 }}} years older than Hillary, we have

{{{R=H+6}}}....eq.1

 if in {{{8}}} years the sum of their ages will be {{{74}}}, we have

{{{(R+8)+(H+8)=74}}}....eq.2......substitute {{{R}}}
{{{H+6+8+H+8=74}}}
{{{2H+22=74}}}...divide by {{{2}}}
{{{H+11=37}}}
{{{H=37-11}}}
{{{H=26}}}
go to
{{{R=H+6}}}....eq.1....substitute {{{H}}}
{{{R=26+6}}}
{{{R=32}}}

answer: Ricardo  is {{{32}}} years old now
