Inquality for Twenty seven is smaller than five times a number increased by seven

Answer 1

The words "is smaller than" imply less than or the symbol, <

If we use x to represent the number, then

27 < 5x + 7

To solve this inequality, use inverses operations:

27 -7 < 5x + 7 - 7

20 < 5x

20/5 < 5x/5

4 < x

This can be interpreted as "all the numbers that are greater 4" are solutions to this inequality.
