Question

How to do 6b - 8 - 5b=

Answer 1

b = 8

Since 6b and 5b have the same variables, you can subtract them both. 1b, but I'd perfer just b. Then, swap the -8 to the other side. It makes it positive. So it's b = 8.

Answer 2

combine like terms which would make it -
-b - 8 =0

add 8 to both sides -

-b = 8

divide both sides by -1 to get b positive which gives you the answer of

b = 8
