Answer:
B = 12
Step-by-step explanation:
Question is
+ 8 = 11
This is a multi-step equation. Multi-step equations involve doing reciprocals of operations, or the opposite of '+', '-', '/ (division)', and '· (multiplication)', to solve for a variable.
For your equation,
+ 8 = 11, we first need to subtract 8 from both sides, since the left side currently contains an 8. This gets rid of the 8 on one side and (11 - 8), which is 3, on the other side.
We now have an equation that is
= 2. Multiplying both sides by 4, we get b on one side and 12 on the other, making our equation b = 12.
