Answer:

j=76 and k=65

Step-by-step explanation:

$j + k = 141 \\ 7x + 13 + 83 + - 2x = 141 \\ 96 + 5x = 141 \\ 5x = 141 - 96 \\ 5x = 45 \\ x = \frac{45}{5} \\ x = 9 \\ j = (7 \times 9 + 13) \\ j =76 \\ k = 83 - 2(9) \\ = 83 - 18 \\ = 65$

Kim is 5 years older than her brother Jack. If the sum of their ages is 21, find each of their ages.

yarga [219]

Answer:

Kim is 13
Jack is 8

Step-by-step explanation:

Let k represent Kim's age. Then Jack's age is k-5 and the total of their ages is ...

k + (k -5) = 21

2k = 26 . . . . . . . add 5, collect terms

k = 13 . . . . . . . . . divide by 2; Kim's age

k -5 = 8 . . . . . . . Jack's age

Kim is 13; Jack is 8.
