-1+8z=-73

Answer 1

To solve the equation -1 + 8z = -73, you want to isolate the variable z.

First, you can add 1 to both sides of the equation to get rid of the -1 on the left side:

-1 + 1 + 8z = -73 + 1

This simplifies to:

8z = -72

Next, divide both sides of the equation by 8 to solve for z:

8z/8 = -72/8

This simplifies to:

z = -9

Therefore, the solution to the equation -1 + 8z = -73 is z = -9.
