Question

solve for x: |x+9|=17

solve for n: |3n+5|=7

Answer 1

x = 8
17- 9 = 8
x = 8
n = 2/3

Answer 2

When solving for absolute value take the equation and make it equal the value and the negative value of the solution...then solve for x.

Answer 3

Thus the first equation we need to solve x+9 = 17 and x+9 = -17

Answer 4

Let's no just give all the solutions to these.
@blondey_315 needs help not just answers.

Answer 5

We should let her try to answer some of them.

Answer 6

I just finished a lesson on this

Answer 7

for |3n+5|=7

|3n+5|=7
(3n+5)^2 = 7^2
3n+5 = + - sqrt(7^2)
3n + 5 = + - 7

So
3n + 5 = 7
n = (7-5)/3 = 2/3

or
3n+5 = -7
3n = -7-5
n =-12/3
n = -4

Answer 8

Yes please! Those answers werent on the answer choices either

Answer 9

Thus the first equation we need to solve x+9 = 17 and x+9 = -17

Answer 10

What are the answer choices? That would help us out a bit.

Answer 11

When solving for absolute value take the equation and make it equal the value and the negative value of the solution...then solve for x.

Answer 12

Thank you!

Answer 13

sorry for

|x+9|=17
(x+9)^2 = 17^2
x+9 = + - sqrt(17^2)
x+9 = + - 17
so x = 17 - 9 = 8
or x = -17-9 = -26

Answer 14

x = -16 or x = -2 for first absolute value equation.

Answer 15

SO the answer is

X = 8 or X = -26
and
n = 2/3 or n = -4

Answer 16

Why are you making this more difficult than it has to be?

Answer 17

You are welcome

Answer 18

Who?

Answer 19

@pip_pip123 the answer choices for the first one is
(8, 26)
(8, -26)
(-8, 26)
(-8, -26)

Answer 20

Oh this is much easier

Answer 21

(8,-26)

Answer 22

|a+b| = c thus a+b=c and a+b = -c

Answer 23

@blondey_315 : get it baby?
