Solve 5x+ c = k for x. A. X = k + c over 5
B. X= k - c over 5
C. x = 5(k+ c)
D. x = 5(k-c)

x =  (k-c)/5

Step-by-step explanation:

5x+ c = k

Subtract c from each side

5x+ c-c = k-c

5x = k-c

Divide each side by 5

5x/5 = (k-c)/5

x =  (k-c)/5

Step-by-step explanation:

5x + c = k ( take "c" over to the otherside )

5x = k - c ( divide by 5 on both sides, to get rid of the 5 in 5x)

k - c

x =

5
