You can put this solution on YOUR website!
I'll do numbers 1 and 3 then you can use these as a guide to solve the others!
1)
3a%2B7%3C16 Subtract 7 from both sides of the inequality.
3a%3C9 Divide both sides by 3.
a%3C3
3)
20-3s%3E7s Add 3s to both sides of the inequality.
20%3E10s Divide both sides by 10.
