Which number line represents the solutions to |x + 4| = 2?
Answered by admin @
The given equation is,
|x + 4| = 2
To solve an absolute value equation , first step is to remove the absolute value sign.
An absolute vaue always give a positive result whether the expression inside the absolute sign is positive or negative.
Hence, to remove an absolute value we will take both positive an negative. Therefore,
x + 4 = 2 and x + 4 = - 2.
So, x = 2 -4 and -2 - 4.
x = -2 and -6.
So, first choice is correct.
