Answer:
c. 3x + 15
The son is currently 12 years old.
The father is currently 42 years old.
Step-by-step explanation:
x = the son's age 2 years ago
x + 2 = the son's age in the present
x + 5 = the son's age 3 years from now
f = the father's age 2 years ago = 4x
f + 2 = the father's age in the present = 4x + 2
f + 5 = the father's age 3 years from now = 3(x + 5) = 4x + 5
*3(x + 5) when distributed is equivalent to 3x + 15
4x + 5 = 3x + 15
x + 5 = 15
x = 10
This means that:
Present age of the son: (10) + 2 = 12 years old
Present age of the father: 4(10) + 2 = 42 years old
