It has infinitely many solutions....because all real numbers satisfy the equation.

Good luck mate :P

Answer:

The correct option is 4. The given equation has infinitely many solutions.

Step-by-step explanation:

The given equation is

[tex]4.5z=4.5z-6.25+6.25[/tex]

This equation can be written as

[tex]4.5z=4.5z+0[/tex]

[tex]4.5z=4.5z[/tex]

Subtract 4.5z from both the sides.

[tex]4.5z-4.5z=4.5z-4.5z[/tex]

[tex]0=0[/tex]

This statement is free from z and LHS=RHS, it means the this statement is true for any value of z.

Therefore the given equation has infinitely many solutions and the correct option is 4.
