Answer 1

any particular one?

Answer 2

do you have a specific problem in mind?

Answer 3

5x+10>(or equal to) 10 and 7x-7 <(orequalto) 14

Answer 4

i don't understand how to do it exactly.

Answer 5

5x + 10 >= 10 -- subtract 10 from both sides
5x >= 10 - 10
5x >= 0 -- divide by 5
x >= 0/5
x >= 0

7x - 7 <= 14 -- add 7 to both sides
7x <= 14 + 7
7x <= 21 -- divide by 7
x <= 3

so we have x greater or equal to 0 and x less then or equal to 3
which can be written like : 0 <= x <= 3
