She received $2
--
8x2= 16
So if 8 yuan equals $1 then 16 divided by 8 would be $2, hope this helped.
1. Distribute the -2x with the (x+3)
2.Multiply (x+1) and (x-2) which is (x2- x -2)
So far it should look like (-2x^2 -6x) - (x^2-x-2)
3. Distribute out the negative
Should look like this -2x^2 -6x - x^2+x+2
4. Lastly combine like terms
Your result should be:
-3x^2 - 5x + 2
Hope this helps!

Answer:
Y=0.2
X=0.9
Step-by-step explanation:
-6x+5y=1
+6x -> 5y=1 -> y=0.2
6x+4y=-10
+6x -> 12x+4y=-10
12x+4*0.2=-10
12x+0.8=-10
-0.8
12x=-10.8
x=0.9
