Answer:
C
Step-by-step explanation:
To solve for x, we have to get x by itself. To do this, perform the opposite of what is being done to the equation.
6x+c=k
First, subtract c from both sides. c is being added to 6x, so we subtract, because subtraction is the opposite of addition.
6x+c-c=k-c
6x=k-c
Next, divide both sides by 6. 6 and x are being multiplied, therefore we divide. Division is the opposite of multiplication.
6x/6=k-c/6
x=k-c/6
So, choice C is correct.
