Full solution

Q. Solve for r \mathrm{r} .\newliner10=8 \frac{r}{-10}=-8 \newlineAnswer: r= r=
  1. Multiply by 10-10: Multiply both sides of the equation by 10-10 to solve for r.\newline(r10)×(10)=8×(10)(\frac{r}{-10}) \times (-10) = -8 \times (-10)
  2. Simplify equation: Simplify both sides of the equation. r=80r = 80
