Solution:
Given:
[tex]3.Z=6[/tex]To get the whole number that will make the equation true, we solve for Z.
[tex]\begin{gathered} 3.Z=6 \\ 3\times Z=6 \\ \text{Dividing both sides by 3,} \\ \frac{3Z}{3}=\frac{6}{3} \\ Z=2 \end{gathered}[/tex]
Therefore, the whole number that will make the equation true is 2.
Hence,
[tex]Z=2[/tex]
