Let x = Edna's age
then it follows that (x + 1) is Ellie's age and (x + 2) is Elsa's age
We can now write and equation for the sum of their ages equal to 108:
x + (x + 1) + (x +2) = 108 simplify the left side
3x + 3 = 108 subtract 3 from both sides
3x = 105 divide both sides by 3
x = 35
Edna is 35, Ellie is 36, and Elsa is 37

Answer:
-3 =x
Step-by-step explanation:
6x+18 = 5(3x+9)
Distribute the 5
6x+18 = 15x+45
Subtract 6x from each side
6x+18-6x =15x-6x +45
18 = 9x+45
Subtract 45 from each side
18-45 =9x+45-45
-27 = 9x
Divide by 9
-27/9 = 9x/9
-3 =x
Answer:
14 8/15
Step-by-step explanation:
6 5/15 + 8 1/5 = 14 8/15
(you see how many times [8 1/5] can go to get to __3/15)
