Question

Which steps are needed to solve this equation?

Answer 1

B = 15.

15 + 6 = 21

hope this helps :)

Answer 2

Answer:

A- Subtract 6 from both sides of the equation.  The answer is b= 15.

For this equation, you need to do the opposite of the number in the same side of the variable. So, there is a +6. To get rid of the +6, you need to be -6.

6-6=0

21-6=15

You will be left with b on one side, and then 15 on the other side.
