Question

2(j+k)=m
Solve for k

Answer 1

Hmm so we want to isolate \(\large k\).

Let's start by dividing both sides by 2,\[\large \frac{2(j+k)}{2}=\frac{m}{2}\]

Hmm what happens to the 2's on the left side?

Answer 2

I probably would have gone a different way about it because I just manage to be difficult about that. If you Foil out 2 into j and k your result will be.

2j + 2k = m

Then you can subtract 2j resulting in

2k = m - 2j

after this you can divide out the 2 with the k.

k = m/2 - j.
