Respuesta :
Since you have 7 times u. You would have to divide by 7 on both sides. So using keep change flip, since you would now have -14/3 / 7/1 (any whole number by itself it automatically over one) you would keep -14/3, but you would change that division sign into a multiplication sign, and you would flip 7/1, so now it’s 1/7. So, -14/3 x 1/7 would be -14/21. Simplify -14/21. -14/21 would be simplified by 7. And finally you would get -2/3. So, your answer is -2/3.
