Question 1169014
Write an equation for each statemen
:
“W” is 3 years younger than “S”’s age.
w = s - 3 
In five years, the sum of their ages will be nineteen. 
(w+5) + (s+5) = 19
w + s + 10 = 19
w + s = 19- 10
w + s = 9
from the first equation, replace w with (s-3)
(s-3) + s = 9
2s = 9 + 3
s = 12/2
s = 6 yrs old 
therefore
w = 3 yrs old
:
How old is “W” now? 3 yrs old
:
Check; in 5 yrs w will be 8 and s will be 11, a total of 19
