# ALG2!

posted by .

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

• ALG2! -

add 3 k to each side

-3k-8>=5k
-8>=8k
divide each side by 8

-1>=k or k<=-1

• ALG2! -

- 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
