May someone me with this question and explain?

You want to have your x alone so you would get rid of the 3. to do that you must do the opposite of what it's saying which it is multiplying so you would divide 3 and do it on both sides. so 3/3 cancels eachother out and now you have to divide 29 and 3 and that is what x equals

You're trying to solve for x (get x by itself) so you divide 3x by 3, and what you do on one side you do to the other so you divide 29/3 which equals (x=9.66666667)

128/3reason being 5 and 1/3 = 16/316/3 • 2/3 = 32/31 and 1/3 = 4/3 32/3 • 4/3 this will equal 128/3
