Solve for r. (r+8)/(7)lt -1 square

To solve the inequality $\frac{r+8}{7} < -1$, we need to isolate the variable $r$.<br /><br />Step 1: Multiply both sides of the inequality by 7 to eliminate the denominator.<br />$7 \cdot \frac{r+8}{7} < 7 \cdot (-1)$<br />$r + 8 < -7$<br /><br />Step 2: Subtract 8 from both sides of the inequality to isolate $r$.<br />$r + 8 - 8 < -7 - 8$<br />$r < -15$<br /><br />Therefore, the solution to the inequality is $r < -15$.
