In January of the year 2000, Sharon was one more than eleven times as old as her son, Jordan.
In January of 2009, she was seven more than three times as old as him. How old was Jordan in January of 2000?
:
Let j = J's age in 2000
Let s = S's age in 2000
:
write an equation for each statement:
:
"In January of the year 2000, Sharon was one more than eleven times as old as her son, Jordan."
s = 11j + 1
:
In January of 2009, she was seven more than three times as old as him."
they are both 9 yrs older, therefore:
s + 9 = 3(j+9) + 7
s + 9 = 3j + 27 + 7
s + 9 = 3j + 34
s = 3j + 34 - 9
s = 3j + 25
Replace s with (llj+1) from the 1st statement
11j+1 = 3j + 25
11j - 3j = 25 - 1
8j = 24
j =
j = 3 yrs old, J's age in 2000
;
:
Check this solutions by finding S's age in 2000
s = 11(3) + 1
s = 34 in 2000
:
Check in the statement:
" In January of 2009, she was seven more than three times as old as him.
34 + 9 = 3(3+9) = 7
43 = 36 + 7
