Answer:

B. 8=2+2a and 3=a

Step-by-step explanation:

1. Look at the scale. On the left side we have 8, on the right side we have 2a + 2.

The two balance each other out perfectly, therefore they're equal.

2. We write our equation.

8=2a+2

3. we substract 2 from the right side so only the '2a' will be left. but if we do something to the right side, we do the same to the left. So, -2 from both sides.

8=2a+2 /-2

6=2a

4. Now we know that 2a=6, but we need to know much much one 'a' is, so we divide by 2.→ divide both sides by 2, so only the 'a' is left on one side, and only a number on the other.

6=2a. /÷2

3=a → this is your answer.
