Question 948342

let Tracy's age be {{{x}}}
when {{{32}}} is subtracted from {{{3}}} times Tracy's age which is {{{3x}}}, the result is (means equal to) Tracy's age;

so, we have {{{3x-32=x}}}...solve for {{{x}}}

 {{{3x-x=32}}}

 {{{2x=32}}}

{{{x=32/2}}}

{{{x=16}}}

Tracy is {{{16}}} years old

check given conditions:

{{{3x-32=16}}}
{{{3*16-32=16}}}
{{{48-32=16}}}
{{{16=16}}}
