Solve equation. check solution. round the solutions to the nearest hundredth if necessary

B + 4b = 8

You have to combine the like terms and then divide both sides by the coefficient to isolate the variable b. 

b + 4b = 8
5b = 8
(5b / 5) = 8 / 5
b = 1.6

Since it says to round to the nearest hundredth, I would just put a zero right after the tenths place. 

b = 1.60

Try a or d, hope that
