# 1

y%2B3%3E7 Start with the given inequality.


y%3E7-3 Subtract 3 from both sides.


y%3E4 Combine like terms on the right side.


----------------------------------------------------------------------

Answer:

So the solution is y%3E4


Here's the graph of the solution set






# 2


d%2F3%3E15 Start with the given inequality.


cross%283%29%28d%2Fcross%283%29%29%3E3%2815%29 Multiply both sides by 3.


d%3E45 Multiply.


----------------------------------------------------------------------

Answer:

So the solution is d%3E45


Here's the graph of the solution set





# 3

You have a typo in there somewhere?


# 4

24%3C+14%2Bk+ Start with the given inequality


24-14%3Ck+ Subtract 14 from both sides.


10%3Ck+ Combine like terms.


k%3E10 Rearrange the inequality


So the solution is k%3E10

Here's the graph of the solution set

1. y+3>7
Subtract 3 from both sides to get:
y > 4
---------------------
2. D/3 > 15
Multiply both sides by 3 to get:
D > 45
----------------------
3. x/2 -6)0
Comment: This one is garbled.
--------------------------------
4. 24< 14+K
Subtract 14 from both sides to get:
10 < K
--
Read from right to left but write from left to right to get:
K > 10
