Solve for r. {:[-13=(r)/(9)+8],[r=◻]:}

Write Equation: Write the original equation. We have the equation -13 = r/9 + 8. Our goal is to solve for r.Subtract to Isolate: Subtract 8 from both sides of the equation to isolate the term with r. -13 - 8 = r/9 + 8 - 8 This simplifies to -21 = r/9.Multiply to Solve: Multiply both sides of the equation by 9 to solve for r. -21 × 9 = (r/9) × 9 This simplifies to -189 = r.

Q. Solve for

r

\newline

\begin{array}{l} -13=\frac{r}{9}+8 \\ r=\square \end{array}

Write Equation: Write the original equation. $\newline$ We have the equation $-13 = \frac{r}{9} + 8$ . Our goal is to solve for $r$ .
Subtract to Isolate: Subtract $8$ from both sides of the equation to isolate the term with $r$ . $\newline$ $-13 - 8 = \frac{r}{9} + 8 - 8$ $\newline$ This simplifies to $-21 = \frac{r}{9}.$
Multiply to Solve: Multiply both sides of the equation by $9$ to solve for $r$ . $\newline$ $-21 \times 9 = \left(\frac{r}{9}\right) \times 9$ $\newline$ This simplifies to $-189 = r$ .
