Test 7 Section 3 - #13 (page 772)

For this question, we'll start by just putting in the values they gave us: a = 2 and c = 3. So now the original equation reads:

2b + b = 2 + 2(3)

Do the multiplication first:

2b + b = 2+6

...then add everything up:

3b = 8

and finally, divide both sides by 3:

b = 8/3

So your answer is 8/3 (or 2.66 or 2.67)!
