$j=0$

This requires a lot of moving around and negative knowledge.

$-4j+14=-2(2j-7)$

First, we must expand the brackets:

$-2(2j-7) = -4j^2+14$

Then we can move on to changing the numbers around (remember to change the signs:

$-4j+14=-4j^2+14$

$-4j+4j^2=-14+14$

And then simplify from there:

$j=0$

Hope this helped.
