Explanation - instead of adding 28 to each side to get rid of the -28, the student subtracted 28 from each side
Correct Answer - x = 403
Step-by-step explanation:
The student subtracted 28 from each side instead of adding 28 to each side. When you add 28 to each side, you are adding 28 to -28, which makes it 0 and disappear. When you subtract 28 from each side, you are adding -28 to -28, which makes it -54, and not 0.
The correct answer can be found by adding 28 to each side, which gives us an answer of x = 403.
Hope this helps!! :)
