The value of variable x in the equation is x = c - k / 3

How to make a variable subject of the formula?

3x+ k = c

let's find x or make it the subject of the formula,

3x + k = c

subtract k from both sides of the equation

3x + k - k = c - k

3x = c - k

divide both sides by 3

3x / 3 = c - k / 3

Therefore,

x = c - k / 3
