None <-- I think this one
One <-- or maybe this one
Two
Infinitely many

Answer 2

\[4z + 2 (z - 4) = 3z + 11\]
Distributive Property
\[4z + 2z - 8 = 3z + 11\]
Like terms
\[6z - 8 = 3z + 11\]
Add 8 to both sides
Subtract 3z from both sides
\[3z = 19\]
\[x = \frac{ 19 }{ 3 }\]

Answer 3

What does that look like to you? :)

Answer 4

Umm... one solution?

Answer 5

Yes.

Two solutions would be if we had plus or minus some number
Infinite solutions would look like 3=3 or x = x
No solutions would look like 3 = 5

Answer 6

Oh okay, thank you!😎
