Question

Reggie is three less than four times his daughter's age. Reggie is 69; how old is his daughter?
a.) 10 B.) 18 C.) 12 D.) 20 help?

Answer 1

Let d be the daughter's age. Then
69 = 4d - 3 ...........(1)
Just solve equation (1) to find d, the daughter's age.

Answer 2

Reggie = 69 (R = 69)
Reggis is 3 less (R = -3) than four times his Daughter's age (R = 4D - 3)
So, 69 = 4D - 3

Answer 3

69 + 3 = 4D
72 = 4D
72/4 = D
