Question

Solve 4x- 9 = k for x.

A. x= k+ 9
B. X=
K-9
4
C. X=
k+9
4
D. x = 4 + 9

Answer 1

The answer is C

Step-by-step explanation:

you first add 9 to both sides, you equation will then be 4x = k+9

you then divide both sides by for to get rid of the four from the left side, that will leave you with the equation of x = k+9 over 4

Answer 2

x = (k+9)/4

Step-by-step explanation:

4x - 9 =k

Add 9 to each side

4x-9+9 = k+9

4x = (k+9)

Divide each side by 4

4x/4 = (k+9)/4

x = (k+9)/4
