Question

Solve for x.
|x| - 4 = 9

(Points : 1)
x = 13
x = 13 or -13
x = 5
x = 5 or -5

Answer 1

okay do you understand absolute value means?

Answer 2

it means any value you give for x it will take the positive value for instance |-3|=3 and |3|=3

Answer 3

so add four to both sides so you get |x|=13

Answer 4

but since it doesnt matter if you use a negative or positive because the absolute value gets rid of it. the answer will be both -13 and 13

Answer 5

does that make sense?

Answer 6

yes a lot of sense, thank you! @DordtCollege
