Answer:
1 1/5 x OR one and on fifth is greater than or equal to x.
Step-by-step explanation:
2/5 x - 4/5
To isolate x, we need to add 4/5 to each side:
6/5 x is what we get
We can simplify it to:
1 1/5 x
Add 4/5 to both sides
X <= 6/5
X <= 1 1/5
it would be a 6 percent mark up :)

=>7x+9-9=9x+5-9
=>7x=9x-4
=>7x-9x=9x-4-9x
=>-2x=-4
=>x=2
=>7x+9=7×2+9=23
=>9x+5=9×2+5=23
