Answer:
The equation has infinitely many solutions
Step-by-step explanation:
Given the equation as
-9(z+8)= -9z-72-----------------open brackets on the left hand side
-9z-72 = -9z-72------------------collect like terms
-9z+9z=-72+72
0=0
z=0, 1, 2,,,,,,,the solutions are endless
The equation has infinitely many solutions
