See the entire solution process below:

Add $color(red)(3/7)$ to each side of the equation to solve for $J$ while keeping the equation balanced:

$J - 3/7 + color(red)(3/7) = 9/14 + color(red)(3/7)$

$J - 0 = 9/14 + (2/2 xx color(red)(3/7))$

$J = 9/14 + ((2 xx 3)/(2 xx 7))$

$J = 9/14 + 6/14$

$J = (9 + 6)/14$

$J = 15/14$
