Please answer this! It confuses me. 20 points for it.

Answer 1

X + 1 = 3
x + 1 - 1 = 3 - 1
x = 2


x + 1 = -3
x + 1 - 1 = -3 -1
x = -4

Answer: x = 2 or x = -4

Answer 2

Since x is in an absolute value equation, it means it could be negative or positive. In order to get three from adding to 1, 2 is one, but because of the absolute value, if you make x -4 then it would be -3 but the absolut value would make it 3. Your answer is both -4 and 2
