❄ 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>.

Let's represent the number of weeks with the variable 'w':
130 + 25w = 600
We subtract both sides by 130:
25w = 470
w = 18.8
We round up:
It will take her 19 weeks.
Sorry it's a bit messy. but I hope you understand and it will help
Where is the graph ??
