3K  8 is less than or equal to 5k .....solve please

add 3 k to each side
3k8>=5k
8>=8k
divide each side by 8
1>=k or k<=1 
 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.
