(2x - y = -2)2
5x - 2y = -7
4x - 2y = -4
Subtract both
x = -3
5(-3) - 2y = -7
-15 - 2y = -7
-2y = 8, y = -4
Solution: (-3,-4)

Answer:
110 = points possible
Step-by-step explanation:
The points received equals the points possible times the percent
99 = points possible * 90%
Changing this to decimal form
99 = points possible * .90
Divide each side by .90
99/.90 = points possible *.90/.90
110 = points possible
