Question 786656
Let n = the number we want
Then we have
(1) {{{5*n + 22 <= 57}}} or
(2) {{{5*n <= 57 - 22}}} or
(3) {{{5*n <= 35}}} or
(4) {{{n <= 35/5}}} or
(5) {{{n <= 7}}}
Let's check this with (1).
Is ({{{5*7 + 22 <= 57}}})?
Is ({{{35 + 22 <= 57}}})?
Is ({{{57 <= 57}}})?Yes
Answer: The number is 7.
