Answer 19

the question isnt even finished....

Answer 20

yes i kno am i going subtract 15 now from both sides

Answer 21

i ment subtract 20

Answer 22

... you do neither of those....

you want to isolate x

so you want to get rid of a -15

this means adding 15

Answer 23

add 15 to both sides right

Answer 24

20<5x-15
+15 +15
is this how it suppose to look when i show my work

Answer 25

the 15 cancels out right so now you have 35< 5x and you divide both sides by 5 right which would leave you x=7

Answer 26

wrong x>7
x is greater than 7 is very different from x equals 7

Answer 27

Answer 28

9x - 3(6 – 5x) = x – 2(3x + 9)
