Answer:

z = - 24

Step-by-step explanation:

Given

- 0.4(0.5z + 4) = 3.2 ( divide both sides by the multiplier - 0.4 )

0.5z + 4 = - 8 ( subtract 4 from both sides )

0.5z = - 12 ( divide both sides by 0.5 )

z = - 24

-0.2z-1.6=3.2 you distribute the -0.4 to 0.5z and 4 and you get the equation above and then you add 1.6 to the other side and get
-0.2z=4.8 you divide both sides by -0.2 and you get z=-5
