Question

Help Please.

Answer 1

\[\huge 1-\frac{z}{5}=9\]Let's start by subtracting 1 from each side,\[\huge 1\color{salmon}{-1}-\frac{z}{5}=9\color{salmon}{-1}\]Which gives us,\[\huge -\frac{z}{5}=8\]

Answer 2

We'll multiply both sides by -5,\[\huge \color{cadetblue}{(-5)}\left(-\frac{z}{5}\right)=8\color{cadetblue}{(-5)}\]Which gives us,\[\huge z=-40\]Understand the steps ok?

Answer 3

yeah i get it i am just not good with the fractions
