Step 1
To find x, we need to remove -8. To do so, add +8 to both sides of the equation.  The equation becomes:
                x -8 +8 = 1 +8

Notice, that -8 and +8 cancels off. There, we are left with:
                        x = 1 +8
Remove -8
Algebra equation x = 1 +8

Step 2
Now, we can simplify the expression by adding
1 with 8.  This gives 9.
