31+8/b=39

1 answer

To solve the equation, we need to isolate the variable b.

We can start by subtracting 31 from both sides of the equation:

8/b = 39 - 31

This simplifies to:

8/b = 8

To get rid of the fraction, we can multiply both sides of the equation by b:

b * 8/b = 8 * b

The b's on the left side of the equation cancel out, leaving us with:

8 = 8b

Now, divide both sides of the equation by 8:

8/8 = 8b/8

This simplifies to:

1 = b

Therefore, the value of b is 1.
