5b = 21 + 4b 5b - 4b = 21 + 4b - 4b b = 21
b= -162
-5b = 55 To get b by itself, divide both sides by -5. (-5b)/(-5) = (55)/(-5) -5 / -5 = 1, 55 / -5 = -11 1(b) = -11 b = -11
it is just 5b
really????? what grade are you in??? 5b b=3 so you plug in 3 for b giving you 5(3) then you multiply because its multiplication and you get 15
