Answer:
x = 
y = 24
Step-by-step explanation:
-3x - 8y = 20 .... (1)
-5x + y = 19 .... (2)
What we can do is take the (2) equation
-5x + y = 19
and solve for y by adding 5x to both sides
y = 24
now that we have y we substitute it in for y in equation (1)
-3x - 8(24) = 20
-3x - 192 = 20
we want to solve for x so we need to get its self.
add 192 to both sides
-3x = 212
now we divide both sides by -3. It's going to be a fraction.
x = 
Hi there!
So here's the important information we know:
He makes 15% comission on everything he sells
He sells a laptop for $293
To find out how much money Daniel makes in comission for the laptop, you need to calculate 15% of $293, which is the same thing as multiplying 15% by $293 :
15% × 293 = $
0.15 × 293 = $
43,95 = $
So your answer is: If Daniel sells a laptop for $293, he makes a comission of $43,95.
There you go! I really hope this helped, if there's anything just let me know! :)
I'm not sure sry maybe you should of studied
