Hey Kayla!
Let me help you out real quick.
x - 2y = 5
-3x + 2y = 7
We need to solve x - 2y =5 for x
x - 2y = 5
x = 5 + 2y
Now substitute 2y + 5 for x in -3x + 2y = 7
-3x + 2y = 7
-3(2y + 5) + 2y = 7
-6y - 15 + 2y = 7
-4y - 15 = 7
-4y = 7 + 15
-4y = 22
y = 22/-4
y = -11/2
Now we need to substitute -11/2 for y in x= 2y + 5
x = 2y + 5
x = 2(-11/2) + 5
x = -22/2 + 5
x = -6
Thus,
The answer is x = -6 and y = -11/2
The correct answer is option D
Good luck with your studies :)
You got it!
