Answer:

Kendra's daughter is 14 years old.

Step-by-step explanation:

If I'm reading this correctly, it says "plus 7 <em>more</em> years." I'm writing my equation based off that phrase being true.

Set up equation:

Variable x = daughter's age

x × 3 + 7 = Kendra

x × 3 + 7 = 49

3x + 7 = 49

3x = 42

x = 14

Check your work:

14 × 3 + 7 = 49

42 + 7 = 49

49 = 49

Correct!
