Numbers e & π...3

How is this absolute value equation done?

| e - πx | = 100

 

[MathLover1]

| e - πx | = 100

e - πx = 100
e - 100= πx
x= (e - 100)/π

-(e - πx ) = 100
-e + πx = 100
πx = 100 +e
x = (100 +e)/π

e - πx = 100
e - 100= πx
x= (e - 100)/π

-(e - πx ) = 100
-e + πx = 100
πx = 100 +e
x = (100 +e)/π

I see that it is done the way as any other absolute value equation. Where did the radical come from?
