Steps to solve:

9z – 6 + 7z = 16z – 6

~Combine Like Terms

(9z + 7z) – 6 = 16z – 6

~Simplify

16z – 6 = 16z – 6

~Subtract 16z to both sides

16z – 16z - 6 = 16z – 16z - 6

~Simplify

-6 = -6

This means that all real numbers are solutions.

Best of Luck!

Answer:

infinite solutions

Explanation:

9z-6+7z=16z-6

Combine like terms

16z - 6 = 16z-6

Subtract 16z from each side

16z-16z -6 = 16z-16z-6

-6 =-6

This is always true so there are infinite solutions
