Question

How do you slice - 4r + 11 = -9Please help

Answer 1

The given equation is

`-4r+11=-9`

First, we subtract 11 on each side

`\begin{gathered} -4r+11-11=-9-11 \\ -4r=-20 \end{gathered}`

Then, we divide the equation by -4

`\begin{gathered} (-4r)/(-4)=(-20)/(-4) \\ r=5 \end{gathered}`

Therefore, the solution is 5.
