6 0

Answer:

x=5

Step-by-step explanation:

so we know the final number is 6 so lets look at the rest of the question:

"twice the difference" so we are going to double the difference of two numbers, one we don't know (x) and the other is 2, so lets put this together and solve:

2(x-2)=6, x-2=3, x=5

Annilee's present age is two-thirds of Jessie's present age. In 14 years the sum of their ages will be 103 years. Find their pre

Butoxors [25]

The present age of Annillee, which is two-thirds of Jessie's present age, is <u>30 years</u>, while Jessie's is <u>45 years</u>.

<h3>How are the ages determined?</h3>

Their present ages can be determined using a system of equations as below.

<h3>Data and Calculations:</h3>

Let the present age of Annilee = ²/₃y

Let the present of Jessie = y

Ages of Annilee and Jessie in 14 years:

Annilee's age = ²/₃y + 14

Jessie's age = y + 14

Sum of their ages in 14 years = ²/₃y + 14 + y + 14

= 103

²/₃y + 14 + y + 14 = 103

²/₃y + y = 75

1²/₃y = 75

y = 75/1²/₃

y = 75/5 x 3

y = 45

<h3>Present Ages:</h3>

Annilee = ²/₃y = ²/₃ x 45 = 30 years

Jessie = y = 45

<u>Check</u>:

²/₃ x 45 + 14 = 44

45 + 14 = 59

Sum of ages in 14 years = 103 (59 + 44) or (30 + 14 + 45 + 14)

Thus, at present, Annilee's age is <u>30 years</u>, while Jessie is <u>45 years</u>.
