Answer:

[tex]z = \frac{47}{7} = 6 \frac{5}{7} [/tex]

Step-by-step explanation:

[tex]7 = \frac{40}{z - 1} \\ 7(z - 1) = 40 \\ 7z - 7 = 40 \\ 7z = 40 + 7 \\ 7z = 47 \\[/tex]

[tex]\boxed{\bold{Answer:{\boxed{\green{\bold{z = \frac{47}{7} = 6 \frac{5}{7}}}}}}} [/tex]

Answer:

z = 5

Step-by-step explanation:

7=40/z-1

- Add 1 to both sides.

8 = 40/z

- Multiply z to both sides.

8(z) = 40/z (z)

8z = 40

z = 5
