Question

Write an inequality that can be solved using the Subtraction Property of Inequality and has a solution of all numbers less than $-3$.

Answer 1

The inequality satisfying all properties given in question is:

$\Rightarrow x+20<17$

$\Rightarrow x+20–20<17–20$ [ Subtract $20$ from both sides ]

$\therefore x<-3$

Hence, $x+20<17$ is the required inequality.
