Solve the equation log.(13-x)= 1.

12

Step-by-step explanation:

13 - x = 1

So isolate x

You need to subtract 13 from both sides to isolate x.

13 - x = 1

13 - 13 -x = 1 - 13

13 -13 equals 0 so it cancels out.

You are left with

- x = 1 -13

-x = -12

Divide the negatives on both sides.

Since a negative divided by a negative equals a positive...

x = 12!
