❄ Hi there,
let us start by considering this: What should we do to get x all by itself?
Since it's
- divided by 4
- multiplied by -1
we should
- multiply (both sides) by 4
- divide (both sides) by -1
So, let's start.
When we divide both sides of an inequality by a negative number, we do "the inequality flip" and <em>flip the inequality sign</em>.
