Answer:
x=5,y=-1
Step-by-step explanation:
5x– 2y = 27
-3x +2y=-17
Add the two equations together to eliminate y
5x– 2y = 27
-3x +2y=-17
----------------------
2x = 10
Divide by 2
2x/2 = 10/2
x = 5
Now find y
-3x +2y = -17
-3(5)+2y = -17
-15+2y =-17
Add 15 to each side
-15+15 +2y = -17+15
2y = -2
Divide by 2
2y/2 = -2/2
y =-1

B: (25) = 0.50x+5
-5 -5
--------------------------------
20 = 0.50x gilberto needs to get 40 correct answers
(divided) / 0.50 /0.50
-------------------------------------
40 = x
C:
y= 0.50 (12) + 5 gilberto will recieve 11 dollars !
