A. X =
k+c
8
B. x = 8(k+ c).
C. x=
k-c
D. x = 80k -c)
SUS

Answer 1

Work done below!

Explanation:

8x + c = k

Subtract c from both sides;

8x = -c + k

Divide both sides by 8;

`x = -(1)/(8)c +(1)/(8)k`

Answer 2

A. x = k+c/8

Explanation:

Might be the most accurate answer based on what I see above.

Since you are solving for x, you would first subtract c on both sides to get 8x = k - c. From there are on out, you would then divide 8 on both sides to get your final answer which is x = k+c/8.
