Solve for y c=3(y+k)

$c = 3 (y + k)$

Rewrite the equation as $3 (y + k) = c$ .

$3 (y + k) = c$

Divide each term in $3 (y + k) = c$ by $3$ and simplify.

Divide each term in $3 (y + k) = c$ by $3$ .

$\frac{3 (y + k)}{3} = \frac{c}{3}$

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3 (y + k)}{3} = \frac{c}{3}$

Divide $y + k$ by $1$ .

$y + k = \frac{c}{3}$

Subtract $k$ from both sides of the equation.

$y = \frac{c}{3} - k$
