Answer:

z = -4

Step-by-step explanation:

Distributive Property: a(b + c) = ab + ac

1. Distribute

0.1z = 0.2(z) + 0.2(2)

0.1z = 0.2z + 0.4

2. Subtract 0.2z from both sides

0.1z - 0.2z = 0.2z - 0.2z + 0.4

-0.1z = 0.4

3. Divide both sides by -0.1 to isolate the variable

-0.1z ÷ -0.1 = 0.4 ÷ -0.1

z = -4
