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)
