Question 1105707
let r = Rick's age
let s =Sherry's
:
Write an equation for each statement
:
 ricks age plus sherrys age is 52 years.
r + s = 52
 ricks age is double sherry's age plus 10 years.
r = 2s + 10
in the first equation, replace r with (2s+10)
(2s + 10) + s = 52
3s = 52 - 10
3s = 42
s = 42/3
 s = 14 yrs is Sherry's age
:
You can find Rick's age, replace s with 14 in either equation
:
