Math · Advanced Math · Medium · Answer it here, explanation included.

$14 j + 5 k = m$

The given equation relates the numbers $j$ , $k$ , and $m$ . Which equation correctly expresses $k$ in terms of $j$ and $m$ ?

ExplanationShow

Choice A is correct. Subtracting $14 j$ from each side of the given equation results in $5 k = m - 14 j$ . Dividing each side of this equation by $5$ results in $k = \frac{m - 14 j}{5}$ .

Choice B is incorrect and may result from conceptual or calculation errors.

Choice C is incorrect and may result from conceptual or calculation errors.

Choice D is incorrect and may result from conceptual or calculation errors.
