Answer: The answer is A. 1.
Explanation:
-11 + 3(b + 5) = 7 Start by distributing the 3. 3xb and 3x5.
-11 + 3b + 15 = 7 Next combine all like terms. -11 + 15.
4 + 3b = 7 You want to get b by itself so move the 4 using subtraction. ..................................4-4 and 7-4
3b = 3 B is still not by itself. Now we must divide 3 by 3 and 3 by 3.
b = 1
Hope this helped. I explained the best I could.
