How many solutions does 9(z+8)=-9z-72 have

zloy xaker [14]

Answer:

1 solution.

General Formulas and Concepts:

Pre-Algebra

Equality Properties

Step-by-step explanation:

Step 1: Define equation

9(z + 8) = -9z - 72

Step 2: Solve for x

Distribute 9: 9x + 72 = -9z - 72
Add 9z to both sides: 18z + 72 = -72
Subtract 72 on both sides: 18z = -144
Divide 18 on both sides: z = -8

Here we see that we will get only 1 solution for z.
