Answer:
B=4
Step-by-step explanation:
B is something called a variable. It is basically a "placeholder" for any number. To solve for the variable, be sure to have the number next to it (or coefficient) to be 1.
Here is how to solve:
[tex]3b=12\\[/tex]
We need to divide both sides by 3 in order to make the coefficient be 1. (Note that a coefficient of 1 means that there is no number next to the variable)
[tex]\frac{3b}{3} =\frac{12}{3}[/tex]
Now, we just solve!
[tex]\frac{3b}{3} =\frac{12}{3} \\b=4[/tex]
Hope this helps! :)
