The sum of a number 8 and twice the number X is 28
hichkok12 [17]

<u><em>ANSWERS ARE AT THE BOTTOM</em></u>

<u><em></em></u>

<u><em>To solve this question, we need to write the questions algebraically. Let's look at the problem first: The sum of a number 8, and twice the number x is equal to 28.</em></u>

<u>Algebraic form:</u>

8 + 2x = 28

<u><em>Lets solve this!</em></u>

<u><em></em></u>

8 + 2x = 28            (Algebraic Form)

2x = 28 - 8             (Subtract 8 from both sides)

2x = 20                  (Divide by 2)

<u><em>x = 10</em></u>                     (Answer)

<u><em>ANSWER:</em></u>

<u><em></em></u>

<u><em>x = 10</em></u>
