Question

C=3(y+k)
solve for y

Answer 1

`y = (C)/(3) - k`

Explanation:

We are given the equation

C = 3( y + k )

We need to isolate y since we are solving for it.

All we have to do, is to divide all terms by 3

`((y+k)3)/(3) = (C)/(3)`

Then we cancel the common factors of 3

`y+k = (C)/(3)`

For the final part, we subtract k from both sides

`y = (C)/(3) - k`

Answer 2

C/3-k=y

Explanation:

C=3(y+k)

Divide each side by 3

C/3=3/3(y+k)

C/3=(y+k)

Subtract k from each side

C/3-k=y+k-k

C/3-k=y
