Answer: Marla is 42 and her daughter is 14
Step-by-step explanation: To solve this problem, let's first go over the information that we are given in the problem.
We know that Marla is three times as old as her daughter so if we use the variable x to represent the daughter's age, Marla's age will be 3x.
Marla's age will be 3x because Marla
is three times her daughter's age.
Since the sum of their ages is 56, we can set up the following equation.
x + 3x = 56.
Combining our x's on the left, we get 4x = 56.
Now to get x by itself, divide both sides by 4 to get x = 14.
So, we just found the daughter's age and she is 14.
Now to find Marla's age, we multiply 3 by 14 to get 42.
So Marla is 42 and her daughter is 14.
