Question

Which statement is true about the equation z = z – 4 + 6? It has no solution. It has one solution. It has two solutions. It has infinitely many solutions.

Answer 1

z=z-4+6
z=z+2
Subtract z from both side
0z=2
Divided 0 for both side
z= undefined. As a result, it has no solution. Hope it help!

Answer 2

It has zero solutions because when u subtract z to the other side u get nothing which equals to 2
