Question

HELPPPPP ! What is the solution set of |2x – 3| – 8 = –1?

Answer 1

I think it is 5 or -5

Answer 2

kinda rusty with these though

Answer 3

Hint: add 8 to both sides

Answer 4

the options are ...
7 or –7
5 or –2
5 or 2
No solution

Answer 5

Hint: if |x| = something, then x is either that something or negative that something

Answer 6

add 8 to both sides

|2x - 3| = 7


then you have 2 equations to solve

2x - 3 = 7 and 2x - 3 = -7

Answer 7

i got -5 and 2 but those aren't in the choices.

Answer 8

I'll solve the first equation and (hopefully) you can use this to solve the second

2x - 3 = 7

2x - 3+3 = 7+3

2x = 10

2x/2 = 10/2

x = 5

Answer 9

So I'm not sure how you got -5 instead of 5

Answer 10

i did +3 by accident -___- lol. THANKS GUYS !
