-2.2+0.3z = 3-0.5z-0.8z

-2.2 = 3-0.5z-0.8z-0.3z

-5.2 = -1.6z

z = -5.2 / -1.6

z = -3.25

[tex]-2.2 + 0.3z= 3 -0.5z -0.8z \\ \\ 0.3z - 2.2 = 3 - 0.5z - 0.8z \\ \\ 0.3z - 2.2 = 3 - 1.3z \\ \\ 0.3z = 3 - 1.3z + 2.2 \\ \\ 0.3z = -1.3z + 5.2 \\ \\ 0.3z + 1.3z = 5.2 \\ \\ 1.6z = 5.2 \\ \\ z = 3.25 \\ \\ [/tex]

The final result is: z = 3.25.
