Question

Solve 7x- c= k for x.

A. x= 7(k+ c)

B. x = k+c/7

C. x=7(k-c)

D. x = k-c/7

Answer 1

It should be x = (k + c)/7, but that isn't there so simply go with B anyways as it is the closest answer.

This was solved by just adding the c to the k side and dividing that (k+c) term by 7. The answer makes (k+c)/7
