Answer 4

thanks! can you explain how you got it?

Answer 5

?

Answer 6

5a < 2 ( - 12) subtracted 12 from both sides to get rid of the 12 on the left

5a < -10

to seperate into the form a = something we need to divide a by 5, but when you do that you will always do it on both sides (just like with the subtracting so we get

a < -10/5

-10/5 is -2

try it on the other one
