Understand the problem

Solve for b b :

8−b=6 8-b=6

Step-by-step solution

First we will move terms so that -b remains remains on the left side of the equation.

We'll move 8 to the right-hand side, making sure to retain the plus and minus signs accordingly:

−b=6−8 -b=6-8

Then we will subtract as follows:

−b=−2 -b=-2

Finally, we will divide both sides by -1 (be careful with the plus and minus signs when dividing by a negative):

−b−1=−2−1 \frac{-b}{-1}=\frac{-2}{-1}

b=2 b=2
