Full solution

Q. Solve for

r

.

1 - 7r > 8

Move Constant Term: Isolate the variable term by moving the constant term on the left side of the inequality to the right side. $\newline$ 1 - 7r > 8 $\newline$ 1 - 1 - 7r > 8 - 1 $\newline$ -7r > 7
Divide by $-7$ : Divide both sides of the inequality by $-7$ to solve for $r$ . Remember that dividing by a negative number reverses the inequality sign. $\newline$ \frac{-7r}{-7} < \frac{7}{-7} $\newline$ r < -1
