Kobotan [32]

Answer:

$\boxed{z = -6.3}$

Step-by-step explanation:

$= > - 2.9 + 4.2z = - 14.73 - 12.74 + 0.3z \\ \\ = > - 2.9 + 4.2z = - 27.47 + 0.3z \\ \\ = > 4.2z - 2.9 = 0.3z - 27.47 \\ \\ = > 4.2z - 0.3z - 2.9 = - 27.47 \\ \\ = > 3.9z = - 27.47 + 2.9 \\ \\ = > 3.9z = - 24.57 \\ \\ = > z = - \frac{24.57}{3.9} \\ \\ = > z = - 6.3$
