Answer 1

its b

Answer 2

Whenever we see a single variable equation, in this case being the variable "b", it is read like this:
"What number multiplied by 3 and added 4, gives me as a result, 16?
Easy enough, all you would have to do is leave alone the variable on one side of the equality and that should be the value of it.
So:
\[3b+4=16\]
if I sustract 4 to both sides, it'll look like this:
\[3b=16-4\]
and dividing by 4 on both sides, we get:
\[b=\frac{ 16-4 }{ 3 }\]
I'll leave the operating to you.

Answer 3

3b+4=16
3b=16-4
3b=12
thus b=12/3
b=4
