Question

help solve pleaseeeee!!!!|x| + 5 = 18 ?
1) 5 or –5
2) 3 or –13
3) 18 or –18
4) 23 or –23

Answer 1

fist isolate the lxl on one side of the equation

Answer 2

absolute value(x) + 5 = 18
av(x) = 13
x= 13 or -13 -- because if you take the absolute value of negative 13 you get positive 13, and the same goes for positive 13

Answer 3

once done you just find the negative version of that number and the positive becuse of the absolute value for x

Answer 4

Because of this there is no choice where you are correct unless choice 2 is really
13 and -13
