<u><em>Hi there! :)</em></u>
<u><em>Answer:</em></u>
<u><em>b=8</em></u>
<u><em>*The answer must have a positive sign.*</em></u>
Step-by-step explanation:
<h2><u>Lesson: Division property of equality</u></h2>
Distributive property: a(b+c)=ab+ac
First, you divide by 7 from both sides of an equation.

Then, you simplify and solve. Divide by the numbers from left too right.

<u><em>Final answer is b=8.</em></u>
I hope this helps you!
Have a nice day! :)
