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
