Hi Haley,
Simplify (8z - 10) ÷ (-2) + 5(z - 1)
---------------------------------------------
(8z - 10) ÷ (-2) + 5(z - 1)
= −4z + 5 + (5)(z) + (5)(−1) (Distribute)
= −4z + 5 + 5z + −5
= −4z + 5 + 5z + −5 (Combine Like Terms)
= (−4z + 5z) + (5 + −5)
= z
Answer: z
---------------------------------------------
Hope This helps :)
