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