We are going to expand :

$4 - 8 j = 14 j + 70$ $4-8j=14j+70$
$4 - 70 - 8 j = 14 j$ $4-70-8j=14j$ ( we substract $70$ $70$ on each side )
$- 66 - 8 j = 14 j$ $-66-8j=14j$
$- 66 = 14 j + 8 j$ $-66=14j+8j$ ( we add $8 j$ $8j$ on each side )
$- 66 = 22 j$ $-66=22j$
$\frac{- 66}{22} = j$ $(-66)/22=j$ ( we divide by $22$ $22$ on each side )
$j = - 3$ $j=-3$
