Answer:
2x + 4 = 3x+ (-1)
Option D)
Step-by-step explanation:
We are given the following in the question:
Let x represent Kim's age
"Bob is 4 years older than twice Kim's age"
Thus, Bob's age =
4 + 2x years
"Paul is 1 year younger than 3 times Kim's age."
Thus. Paul's age is
(3x - 1) years
If Bob's age and Paul's age is equal, we can write:
2x + 4 = 3x + (-1)
Thus, the required expression is
2x + 4 = 3x + (-1)
Option D)
Option D! Â 2x + 4 = 3x + (-1)
The equation can be used to determine Kim’s age will be 2x + 4 = 3x + (–1). Then the correct option is D.
What is the linear system?
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Use the information to write an equation with variables on both sides. Let x represent Kim’s age.
Bob is 4 years older than twice Kim’s age. Then the age of the Bob will be in terms of x.
B = 2x + 4
Paul is 1 year younger than 3 times Kim's age. Then the age of the Paul will be in terms of x.
P = 3x – 1
Bob and Paul are the same age.
B = P
Put the value of B and P, then we have the equation will be
2x + 4 = 3x – 1
2x + 4 = 3x + (–1)
Then the correct option is D.
