Heya there!
Let us learn that we want that variable to be by itself.
To get the variable (b) by itself we need to do some work.
<u>Solving for B:</u>
As we need to get B by itself, we beed to remove the "-19".
To do that, we have to +19 since the -19 is a negative.
This allows us to have B by itself.
b - 19 = -11
+19 +19 to both sides ; whatever action we do to one side we do to the other.
Now, the equation should look like <u>b = 8</u>
We got b = 8 from the adding +19 to both sides. <u>-11 + 19 = 8</u>
Therefore, we are left with<u> b = 8.</u>
