Answer:

Alex is 7, Bella is 11, and Carla is 14

Step-by-step explanation:

Equation is 32=y+2y+(y+4)

To solve:

First combine like terms (the y's)

32=4y+4

Subtract 4 from both sides

28=4y

Divide both sides by 4 to get y alone

7 =y (Alex's age)

Bella is 4 years older than Alex so 7+4 = 11

Carla is 2 times older than Alex so 2 • 7 = 14

Their ages are supposed to add up to 32.

7+11+14

18+14

32
