Answer:

First friend = 21 years

Second friend = 22 years

Third friend =23 years

Step-by-step explanation:

Age of first friend = x

Age of second friend = x+ 1

Age of third friend = x+ 2

Sum of ages = 66

(x) + (x+1) +(x + 2) = 66

3x + 3 = 66

3x = 66-3

3x = 63

x = [tex]\frac{63}{3}[/tex]

x= 21

First friend = x = 21 years

Second friend = x+1 = 21 +1 =22 years

Third friend = x+2 =21 +2 =23 years

Hope this helps.

Answer:

21, 22, and 23 years old.

Step-by-step explanation:

1) x

2) x+1

3) x+2

x + x +1 + x + 2 = 66

3x +3 = 66

3x = 66-3

x = 63/3

x = 21
