Answer:
x = 
, y = 
Step-by-step explanation:
1. Isolate for x in one of the equations:
2x = 9x - 14y
2x-9x = 9x-9x -14y
-7x = -14y
-7x/-7 = -14y/-7
x = 2y
2. Substitute 2y in for x in the second equation:
9(2y) = 40 - 14y
3. Simplify:
18y = 40 - 14y
4. Isolate for y:
18y+14y = 40 -14y+14y
32y = 40
32y/32 = 40/32
y =
5. Substitute the new y-value into the simplified expression x = 2y:
x = 2(5/4)
x =

Answer:
$675
Step-by-step explanation:
Let s represent her Monday sales.
Raisa receives a 7% commission on her sales. In this case the commission was $47.25, representing 0.07s.
Solve for s: Divide both sides of 0.07s = $47.25 by 0.07:
s = $47.25/0.07 = $675.
The dollar value of her sales was $675.
