(Choice C)

Infinitely many solutions

Respuesta :

Answer:

B. Exactly one solution

Step-by-step explanation:

The given equation is:

[tex]20z - 5 - 12z = 10z + 8[/tex]

We group like terms to get:

[tex]20z - 12z - 10z =8+ 5[/tex]

Combine like terms to get:

[tex] - 2z = 13[/tex]

Divide both sides by -2

[tex]z = - \frac{13}{2} [/tex]

The correct answer is B.
