First you need to get x on one side of the equation and to do that subtract 2a from both sides.
28 + 2a = 5a + 7
-2a -2a
28=3a+7

Then we need to get a alone by subtracting 7 on both sides.
28=3a+7
-7 -7
21=3a

Finally divide each side by 3 and you should get a = 7. Hope this helps!

How much medicine should he add to the food?​
quester [9]

Answer:

Paul should give 18 teaspoons of medicine to his dog.

Step-by-step explanation:

It is stated in the question that for every 12 pounds, 3 teaspoons of medicine is to be given to the dog.

This implies that:

12 pounds = 3 teaspoons

1 pound = 3/12 teaspoons

             = 1/4 teaspoons                      <em> ( by cross multiplication )</em>

<em />

<h3>72 pounds = 1/4 * 72 teaspoons</h3><h3>                   = 18 teaspoons</h3><h3 />

Hence, Paul should add 18 teaspoons of medicine to his dog's food.
