I don't think it will do anything to harm your health, however a 4B pencil seems an odd shade to choose for eyebrows. An eyebrow pencil may be a more appropriate texture for application and removal.
ebony pencil, 4B pencil, HBpencil(#2 pencil), 4H pencils
This are the 6 different pencil cases: '''2B, HB, 4A, 4B, 2A, 4C.'''
There is no 4N... 4H = Extremely Hard and will make a light mark. 4B = Extremely Bold and will make a thick and dark mark. HOPE THIS HELPS! :)
If you want. Pencils with higher numbers such as 6Bs give a darker stroke and are softer. So, if you don't mind using a harder, slightly lighter pencil, then go ahead.
That would depend if the pencil were an H or a B. Artist pencils are identified with a number and a letter. H is for hard. A 6H pencil would be harder than a 4H pencil. B is for soft. A 6B pencil would be softer than a 4B pencil.
2a + 4b - 52a + 4b - 52a + 4b - 52a + 4b - 5
8b - 4b = 4b
5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
4b - 1 = -4 + 4b + 3first, simplify and add together what you can.4b - 1 = -1 + 4b4b = 4bbecause 4b is always equal to 4b, the answer is infinite.
Well if it is worded right then 4xb-1+(-4)+4b=4b-1-4+4b=4b+4b-1-4=8b-5
