Answer:
A = 4
Step-by-step explanation:
Assuming the question is asking what <em>a</em> is, then all you have to do is follow a few steps to get the right answer.
1) Use the distributive property to simplify the first part of the equation.
4(2+a) <em>distribute the 4 to what is within the parenthesis, so multiply 4 to what is in the parenthesis. P.S: This also gets rid of the parenthesis.</em>
(8 + 4a)
2) Now your equation looks like 8 + 4a = 24. Now, use <em>inverse operations</em> to isolate <em>a. </em>Inverse operations are basically using the opposite signs and processes to get some parts of an equation to another side.
2a. Subtract 8 from both sides of the equation:
8 + 4a - 8 = 24 - 8.
So now you have 4a = 16.
2b. Divide 4 from both sides of the equation.
4a/4 = 16/4
So now you have a = 4.
Final answer:
A = 4
