Answer:
[tex]\boxed{\bold{z=-60}}[/tex]
Step-by-step explanation:
Switch Sides
[tex]\bold{2+\frac{z}{-6}=12}[/tex]
Subtract 2 From Both Sides
[tex]\bold{2+\frac{z}{-6}-2=12-2}[/tex]
Simplify
[tex]\bold{\frac{z}{-6}=10}[/tex]
Multiply Both Sides By -6
[tex]\bold{\frac{z\left(-6\right)}{-6}=10\left(-6\right)}[/tex]
Simplify
[tex]\bold{z=-60}[/tex]
