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
