Answer:
x = 1 and y = 2 is the solution of the given system of equations.
Step-by-step explanation:
Here, the given system of equations is:
2x + y = 4 ........ (1)
-3x + y = -1 ......... (2)
Now, from (1) y = 4 - 2x
Substitute this value of y in (2), we get
-3x + y = -1 ⇒ -3x + 4 - 2x = -1
or, -5x = -5
or, x = 1
Also, y = 4 - 2x = 4 - 2(1)
= 4 -2 = 2
⇒ y = 2
The point (1,2) is the solution of the given system.
Hence, x = 1 and y = 2 is the solution of the given system of equations.
So this would be yes she does pass the course because 4/5 is bigger than 75
