Question 1140886

let's Renee's age be {{{x}}}

if Renee is one year {{{older}}} than Tom,   Tom's age is {{{x-1}}}

and if Ellen is twice as old is your Renee. Ellen 's age is {{{2x}}}


if the sum of their ages is {{{63}}}, we have 

{{{x+(x-1)+2x=63}}}.......solve for {{{x}}}

{{{x+x-1+2x=63}}}

{{{4x=63+1}}}

{{{x=64/4}}}

{{{x=16}}}->Renee's age

Tom's age is {{{x-1=16-1=15}}}

Ellen 's age is {{{2x=2*16=32}}}


check the sum of their ages:

{{{16+15+32=63}}}

{{{63=63}}}
