Answer:
a. x = 1, y = -2
Step-by-step explanation:
The given equations are 2x + 3y = -4 -------------(1)
x - 2y = 5 -----------------(2)
From the second equation, we get x = 2y + 5
Now plug in x = 2y + 5 in the first equation, we get
2(2y + 5) + 3y = - 4
4y + 10 + 3y = -4
7y + 10 = -4
7y = -14
y = -2
Now plug in y = -2 in x = 2y + 5 to find the x value.
x = 2(-2) + 5
x = -4 + 5
x = 1
Therefore, x = 1, y = -2
Thank you.
