Good luck mate :P

Answer 2

Answer:

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

Step-by-step explanation:

The given equation is

$4.5z=4.5z-6.25+6.25$

This equation can be written as

$4.5z=4.5z+0$

$4.5z=4.5z$

Subtract 4.5z from both the sides.

$4.5z-4.5z=4.5z-4.5z$

$0=0$

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.
