Question

The difference between two numbers is greater than the first number and the sum of

the two numbers is greater than 21. Find the system of inequalities representing the
given situation.

Answer 1

Explanation:

let the numbers be x and y

x-y>x

or -y>0

or y<0

and x+y>21

or if we want to solve further then

y<0

and x+y>21

or y>21-x

or 21-x<y <0

so 21-x<0

or 21<x

or x>21
