Question

I NEED MATH HELP!!!

Answer 1

please show how to solve it

Answer 2

First divide both sides by 3 to get |4x-7| = 5

then you break up that equation to get these two equations:

4x-7 = 5 or 4x-7 = -5

Answer 3

what do you get when you solve 4x-7 = 5 for x ?

Answer 4

First you have to dive both sides by 3.
3/3 | 4x - 7 | = 15/3

Answer 5

divide*

Answer 6

obviously for that you should've gotten 1 and 5.
1 | 4x - 7 | = 5

Answer 7

which is the same as | 4x - 7 | = 5

Answer 8

then you start actually solving the problem by having to add the opposites which is by adding +7 to both sides of the equation ( -7 + 7) and (5 +7)

Answer 9

from this you obviously get 0 from adding -7 + 7 and you get 12 from adding 5 + 7.
4x = 12

Answer 10

you have to divide 4 from each side now so that you can get rid of the number in front of the 4.
4x/4 = x
12/4 = 3


x = 3

Answer 11

but remember you also have to find the second answer to this

Answer 12

so we can start off at | 4x - 7| = -5 (because now we have to change it to a negative 5 instead of a positive 5)

Answer 13

4x - 7 = -5 and then we do the same steps

Answer 14

4x - 7 = -5
+7 +7
4x = 2

4x/4 2/4
4x/4 = x
2/4 = .5

Answer 15

so your final answers are: 3, .5 which i believe was B

Answer 16

yep it was B. so there you go. your welcome.

Answer 17

you're*

Answer 18

Wow thank you soooooo much. Thank you for mapping it out for me!!! It's MUCH easier to understand.

Answer 19

:) no problem. so you understand how i got the answer?
