Choose 1 answer:
No solutions
B
Exactly one solution
Infinitely many solutions

Answer 1

Answer:

exactly one solution: 3/11 = z

Step-by-step explanation:

-2z + 10 +7z = 16z + 7

combine like terms

5z + 10 = 16z + 7

       -7            -7

5z + 3 = 16z

-5z         -5z

3 = 11z

/11   /11

3/11 = z
