Answer: x=3
Step-by-step explanation:
<u> 1 </u>(x-15)+2x=16
3
<u> 1 </u>x-15+2x=16
3
<u>x-45+2x=16</u>

x-15+6x=16
7x=15+16
x=<u> 21 </u>

x=3
So I am assuming that there is a 20% off sale on an item that is 20$.
Edit: I read the question wrong, the 2nd thing I wrote down is the correct answer, it will be $24 after the markup.
Get into y=mx+b form
m=slope
3x-5y=10
minus 3x from both sides
-5y=-3x+10
divide both sides by -5
y=-3/-5x+10/-5
y=3/5x-2
the slope is 3/5
