Answer:
x ∈ {0, 10}
Step-by-step explanation:
It is convenient to divide by 3:
0 = |x -5| -5
Add 5:
5 = |x -5|
Unfold the absolute value:
±5 = x -5
Add 5:
5+5 = x = 10 . . . . use the "plus" of "plus or minus"
5 -5 = x = 0 . . . . use the "minus" of "plus or minus"
The values of x that make the equation true are 0 or 10.
