Question

solve for r.
-13 = \\(\frac{r}{9}\\) + 8
r = \boxed{}

Explanation:

Step1: Subtract 8 from both sides

To isolate the term with \( r \), we subtract 8 from both sides of the equation \(-13=\frac{r}{9}+8\). This gives \(-13 - 8=\frac{r}{9}+8 - 8\), which simplifies to \(-21=\frac{r}{9}\).

Step2: Multiply both sides by 9

To solve for \( r \), we multiply both sides of the equation \(-21=\frac{r}{9}\) by 9. So, \(-21\times9=\frac{r}{9}\times9\), which simplifies to \( r=-189 \).

Answer:

\( r = -189 \)
