Example:
8x + 5 < 77 -5 -5 72 8 x < 9 9 Now you try! 9k - 54 < 93 + k When multiplying or dividing by a negative number,
flip the inequality sign.

Example: -8n -4 < 5 -4 -4 1 -8n -8 -8 n > 0.125 0.125 9x +87-9 < 68 76 - 86 > 8 - 75 + 9 five inequality signs < less than
> greater than
< less than equal to
