<u><em>Answer: D. X=22 and 22=X. *The answer must have a positive sign.*</em></u>
Explanation:
<u><em>Addition property of equality is adding the same number to both sides of an equation </em></u><u><em>"it's does not change the equation."</em></u>
<u><em>First, add 28 both sides of an equation.</em></u>
2x-28+28=16+28
<u><em>Then, simplify.</em></u>
28+16=44
2x=44
<u><em>Next, divide by 2 both sides of an equation.</em></u>
2x/2=44/2
<u><em>And finally, simplify by equation. And divide by the numbers.</em></u>
44/2=22
22*2=44
44/22=2
2*22=44
<em><u>X=22 and 22=X</u></em>
Hope this helps!
Thanks!
Have a great day!
