Kendrick is 1 year older than 3 times his daughter's age. In 4 years, he will be 7 years less than 3 times as old as his daughter will be. Write a system of equations that can be used to solve this problem, where k is Kendrick's age now and d is his daughter's age now.

Respuesta :

Answer:

k = 1 + 3d

k + 4 = 3(d + 4) -7

Step-by-step explanation:

Firstly, we need to use variables to represent the present ages of Kendrick and his daughter. Let Kendrick’s age be k and his daughter’s age be d.

From the first statement: Kendrick is 1 year older than 3 times his daughter age. This mathematically means:

K = 1 + 3d (I)

Secondly: in four years time, he will be 7 years less than 3 times as old as his daughter. Mathematically:

k + 4 = 3(d + 4) -7 (ii)
