Question

hi

Answer 1

So either 4x-3=5 or 4x-3=-5, by the definition of absolute value. So then x={2,-1/2}.

Answer 2

So, in order to solve absolute value equalities you need to set up two equations.
4X-3 = 5
4X-3 = -5
Using some basic algebra we get X = 2 or X = -1/2.

Answer 3

CAN YOU EXPLAIN A LITTLE BETTER? PLEASE, IM STUCK ON THIS

Answer 4

This video will help.

Answer 5

The absolute value means that the thing on the inside can be either the positive or the negative, right? Since absolute value of 5 is 5 and absolute value of -5 is also 5, so both work. And so we just set up the two equations equal to both 5 and -5 and solve algebraically.

Answer 6

Maybe you could tell us exactly what you're confused about? And @Nightarrow, that's not really helpful. KhanAcademy isn't nearly the same as what OpenStudy is all about.

Answer 7

First you add the 3 so it's then | 4x | = 8, then you divide the 4, so the answer is x = 2

Answer 8

I`m sorry @OakTree, I just felt that KhanAcademy was a helpful source and could help @iribeiro1602 with her dilemma.

Answer 9

I LIKE KHAN ACADEMY A LOT LOL!

Answer 10

@LillianM, that's invalid. You can't take out the absolute value like that.

Answer 11

SO THE ANSWER WILL BE x={2,-1/2}

Answer 12

?

Answer 13

Yeah it will.

Answer 14

THANK YOU GUYSS! :)
