because there is somthing in the air that is called that and it can kill you if you have 1 of the rare blood type so get cheked out by a doctor every 10 mouths and if you havnt your going to die :/
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.
Oxygen and boron can react to form boron oxide. The reaction typically produces boron trioxide (B2O3) when boron is burned in air or oxygen.
Well if it is worded right then 4xb-1+(-4)+4b=4b-1-4+4b=4b+4b-1-4=8b-5

4b-b
2a-6a-a=b+4b-4b -5a=5b-4b -5a=1b a=-5 b=1
-4b+2 = 18 -4b = 18-2 -4b = 16 b = -4
The expression 18 plus 6 plus 4b simplifies to 24 + 4b.
5-4b = 1
