Question

PLEASE HELP ASAP!! I NEED THE ANSWER

Answer 1

`\huge \: x = \{ - 2, 12 \}`

Explanation:

to understand this

you need to know about:

• absolute value
• absolute value equation
• PEMDAS

tips and formulas:

• 
  `|u| = a < = > u = ±a \: (always)`

given:

• 
  `|c - 5| = 7`

to find:

• 
  `c`

let's solve:

`|c - 5| = 7`

`step - 2 : \\ rewrite \: the \: absolute \: value\: equation \: as \: two \: separare \: equation`

`c - 5 = 7 \\ c - 5 = - 7`

`step - 3 : simplify`

`c = 12 \\ c = - 2`

`\huge \: x = \{ - 2, 12 \}`

Answer 2

D. {-2,12}

Explanation:

you have to the equation with the answer being both negative and positive because it is absolute value...

c-5= 7 c-5= -7

add 5 to both sides on both equations

c-5= 7 and c-5= -7

+5 +5

c= 12 and c= -2

This probably doesnt help that much i tried.... :)
