Answer:
[tex]r=-9[/tex]
Step-by-step explanation:
We are given the equation
[tex]7r=-63[/tex]
In order to solve for r, we must divide each side by 7
[tex]r=\frac{-63}{7}[/tex]
This then simplifies to
[tex]r=-9[/tex]
The answer is -9 you can solve this by dividing 7 to get R alone since you are solving for that variable.
