$r < - 5$ $r< -5$

Solve:

$- 231 > 7 (7 r + 2)$ $-231>7(7r+2)$

Expand the right-hand side.

$- 231 > 49 r + 14$ $-231>49r+14$

Subtract $14$ $14$ from both sides.

$- 231 - 14 > 49 r$ $-231-14>49r$

$- 245 > 49 r$ $-245>49r$

Divide both sides by $49$ $49$ .

$- \frac{245}{49} > r$ $-245/49>r$

Simplify.

$- 5 > r$ $-5>r$

Switch sides.

$r < - 5$ $r< -5$
