add 3 k to each side
-3k-8>=5k
-8>=8k
divide each side by 8
-1>=k or k<=-1
-3K - 8 is less than or equal to 5k .....solve please

- 3 k - 8 < = 5 k Subtract 5 k to both sides
- 3 k - 8 - 5 k < = 5 k - 5 k
- 8 k - 8 < = 0 Add 8 to both sides
- 8 k - 8 + 8 < = 0 + 8
- 8 k < = 8 Divide both sides by - 8

Remark :
If you multiply or divide both sides of an inequality by a negative number, you must reverse the direction of the inequality sign.

k > = - 1
- 3 k - 8 - 5 k < = 5 k - 5 k
- 8 k - 8 < = 0 Add 8 to both sides
- 8 k - 8 + 8 < = 0 + 8
- 8 k < = 8 Divide both sides by - 8
