) $2,5z - 33,6 = 0,4z$

Explanation:

Step1: Subtract \(0.4z\) from both sides

\(2.5z - 0.4z - 33.6 = 0.4z - 0.4z\)
\(2.1z - 33.6 = 0\)

Step2: Add 33.6 to both sides

\(2.1z - 33.6 + 33.6 = 0 + 33.6\)
\(2.1z = 33.6\)

Step3: Divide both sides by 2.1

\(z=\frac{33.6}{2.1}\)
\(z = 16\)

Answer:

\(z = 16\)
