Question

Kim is x years old . jordan is 7 year older than kim. four times jordans age is equal to 200

Answer 1

So we don't know how old Kim is.
Jordan is 7 years older, and 4x of Jordan's age equals to 200.

So Jordan is 50 because 50 x 4 = 200.
Back to Kim, 50 - 7 = 43. Kim is 43. 

Now, you write the equation. I helped you alot. 

Answer 2

Kim is x
Jordan is x+7
Jordan x 4 = 200

Therefore 4(x+7) = 200
X+7 = 50
X = 43

Kim is 43, Jordan is 50.
