Yolanda is 4 years younger than 3 times her daughter's age. the sum of their ages is greater than 88. what is the youngest age yolanda's daughter can be? enter your answer, as a whole number, in the box.

Let's say Yolanda's age = y
Let's also say her daughter's age = d

You can then write the first sentence as this:
y = 3d - 4

Then you can write it as (for the sum of there ages):
d + 3d - 4 = 88
Then solve it:
4d - 4 = 88

Then add 4 on to both sides:
4d - 4 + 4 = 88 + 4
Then solve it:
4d = 92

Then divide both sides by 4:
4d/4 = 92/4

Then solve:
d = 23

The youngest her daughter can be is 23,
Hope this helps! :)
