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