5z + 4 = 4 + 5z?

A.
one solution

B.
no solution

C.
an infinite number of solutions

D.
z = 20

Answer 1

Subtract 5z to both sides..what's 5z - 5z?

Answer 2

0 right?

Answer 3

They get cancelled.

Answer 4

So i would say B?

Answer 5

Yes..well your equation is 5z + 4 = 4 + 5z

It's the same thing on both sides..therefore they're the same line..so infinitely many solutions.

Answer 6

5z + 4 = 4 + 5z

They're both 5z + 4.

Answer 7
