Question

Solve 4x- c = k for x.
A. x = k-c/4
B. x = 4(k-c)
C. x- k+c/4
D. x = 4 (k+c)​

Answer 1

A

Explanation:

You would first add c to the side that k is on and then divide k+c by 4 because it is 4x which means they are being multiplied together so you have to divide to get them apart.

Answer 2

C. x= k+c/4

Explanation:

`4x- c = k`

Move -c to the right side and change its sign

`4x = k+c\\`

Divide both sides of the equation by 4

`(4x )/(4) = (k+c)/(4)\\ \\x = (k+c )/(4)`
