Question

2. Kim is x years old. Jordan is 7 years older than Kim. Four times Jordan’s age is equal to 200. (a) Write an equation that could be used to solve for Kim’s age, x. (b) How old is Kim? (c) How old is Jordan?

Answer 1

If Kim is x years old, Jordan will be x years old plus seven.

4(x + 7) = 200 is a given.

a) The formula would be 4x + 28 = 200.

b) The result is 4x = 200 - 28 x = 172/4x = 43.

x + 7 = 43 + 7 = 50 is the age of Jordan.

Explanation:

Kim is thus 43 years old.

Jordan is 50 years old, to put it briefly.

Answer 2

Let, the age of Kim = x
Then, Jordan's age = x + 7

It is given that, 4(x + 7) = 200

a) Equation would be: 4x + 28 = 200

b) Now, 4x = 200 - 28
x = 172/4
x = 43

So, Kim is 43 Years old.

c) Age of Jordan = x + 7
= 43 + 7 = 50

In short, Age of Jordan is 50 Years

Hope this helps!
