How many solutions does the following equation have? -9(z+8)=-9z-72−9(z+8)=−9z−72

The equation has infinitely many solutions

Step-by-step explanation:

Given the equation as

-9(z+8)= -9z-72open brackets on the left hand side

-9z-72 = -9z-72collect like terms

-9z+9z=-72+72

0=0

z=0, 1, 2the solutions are endless

The equation has infinitely many solutions

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.
