To solve this equation, you must multiply by a denominator and then subtract to isolate a variable.

Multiply by 4 on both sides of the equation.

$\displaystyle 4(5 + (k)/(4)) = 4(3)$

$\displaystyle 20 + k = 12$

Subtract 20 from both sides to isolate the k.

20 - 20 + k = 12 - 20

$\boxed{k = -8}$

The final answer is k = -8.
