-1/3 = j/4 - 10/3
add 10/3 to each side
-1/3 + 10/3 = j/4 -10/3 + 10/3
9/3 = j/4
simplify
3 = j/4
multiply each side by 4
4*3 = j/4 *4
12 = j
Answer : j=12
Multiply both sides by the LCD which is 12.
12 * (-1/3) = 12 * j/4 - 12 * 10/3
-4 = 3j - 40
Add 40 to both sides.
36 = 3j
Divide both sides and switch sides.
j = 12
