Question 661686


let Sherry's age be {{{x}}} and Sara's age {{{y}}}

if Sherry is two years younger than Sara, than {{{y=x+2}}} 


if the sum of their ages is {{{46}}}, than {{{x+y=46}}}

solution:

 {{{x+y=46}}},,,substitute {{{y=x+2}}} 

{{{x+x+2=46}}}

{{{2x=46-2}}}

{{{2x=44}}}

{{{x=22}}}...........Sherry's age

{{{y=x+2}}}

{{{y=22+2}}}

{{{y=24}}}...........Sara's age
