Solve 4x- c= k for x.

K + c
A. X =
*=***
B. x = 4(k-c)
C. x = 4(k+ c)
К-с
D. x.

Answer 1

Explanation:

Let's begin the solution by isolating the 4x term:

4x- c= k => 4x = c + k

Now divide both sides by 4:

c + k

x = --------------

4

This does not match Answer C, but would match Answer C if k + c were divided by 4. Answer C, as shown, is incorrect.
