Answer:
z = 20
Explanation:
The given equation is
[tex]\frac{3}{4}z=15[/tex]To solve the equation, we first need to multiply both sides by 4
[tex]\begin{gathered} 4\cdot\frac{3}{4}z=4\cdot15 \\ \\ 3z=60 \end{gathered}[/tex]Then, divide both sides by 3
[tex]\begin{gathered} \frac{3z}{3}=\frac{60}{3} \\ \\ z=20 \end{gathered}[/tex]Therefore, the solution is z = 20
