To solve this equation, we need to set each factor equal to zero and then solve for the variables.
1) 4z - 16 = 04z = 16z = 4
2) 7x + 8 = 07x = -8x = -8/7
3) 2.7 - 0.9x = 0-0.9x = -2.7x = -2.7 / -0.9x = 3
Therefore, the solutions to the equation are z = 4 and x = -8/7 or x = 3.

4z = 16
z = 4
2) 7x + 8 = 0
7x = -8
x = -8/7
3) 2.7 - 0.9x = 0
-0.9x = -2.7
x = -2.7 / -0.9
x = 3
Therefore, the solutions to the equation are z = 4 and x = -8/7 or x = 3.
