Explanation:
To solve this problem, first you have to isolate it on one side of the equation. Remember to solve this problem, multiplication property of equality is multiply both sides of an equation the same number doesn't change the equation.
First, switch sides.
![\displaystyle (z)/(14)=6](https://img.qammunity.org/2020/formulas/mathematics/middle-school/iymh6zvdby6twehlna02pwftsmnmbj5en4.png)
Next, multiply 14 from both sides.
![\displaystyle (14z)/(14)=6*14](https://img.qammunity.org/2020/formulas/mathematics/middle-school/7c2wyfhk444h3zoeg77biggmqu4t2cw8eb.png)
Solve.
![\displaystyle 6*14=84](https://img.qammunity.org/2020/formulas/mathematics/middle-school/eai7ppgo4bs4ecateo96809rmmpn94m93f.png)
Therefore, the correct answer is z=84.
