B.
x + 5 = 55 and x + 5 = –55; {–50, –60}
C.
x – 5 = 55 and x + 5 = –55; {60, –60}
D.
x – 5 = 55 and x + 5 = –55; {–60, –60}

Answer 1

What do you think the answer must be ?

Answer 2

i think its C

Answer 3

No its not C.

Remember this:

\[\large{|x+a| = b}\]

\[\large{\implies x + a = \pm b}\]

\[\large{\implies x + a = b~~\text{or}~~x+a = -b}\]
