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

Step-by-step explanation:

to understand thisyou need to know about:absolute valueabsolute value equationPEMDAStips and formulas: $|u| = a < = u = ±a \: (always)$ given: |c - 5| = 7

to find:

let's solve:

step - 1 : define

|c - 5| = 7

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

$c - 5 = 7 \\ c - 5 = - 7$

step - 3 : simplify

$c = 12 \\ c = - 2$

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

Mathematics

-2x+8=y=x-1
-2x+8=x-1
add 2x to both sides
8=3x-1
add 1
9=3x
divide 3
3=x
sub
y=x-1
y=3-1
y=2

(x,y)
(3,2)
