Question

6 + x is equal to or less than 18

Answer 1

Written in numerical form, it would look a bit like this:

6 + x ≤ 18

≤ means 'equal to or less than'

Answer 2

6 + x ≤ 18

isolate the x, subtract 6 from both sides

x + 6 (-6) ≤ 18 (-6)

x ≤ 18 (-6)

x ≤ 12

x ≤ 12 is your answer

hope this helps
