Hello there!
In this problem we are trying to find the value of b in the given equation: 8 + 3b = -13. To do this, we have to isolate b.
The first step is to subtract 8 from both sides of the equation.
8 - 8 + 3b = -13 - 8
3b = - 21
Next, divide both sides of the equation by 3.
3b÷3 = -21÷3
b = -7
So, -7 is your final answer!
