= 36
Solution = 36
aka
y = 36
Answer:
the plane would fall and crash at 150mph
Step-by-step explanation:
The solution of the equation are as follows:
x = 6 and y = -5
<h3 />
<h3>How to solve the system of equation?</h3>
4x + 5y = -1
-5x - 8y = 10
Therefore,
20x + 25y = -5
-20x - 32y = 40
-7y = 35
y = -5
Hence,
4x + 5(-5) = -1
4x - 25 = -1
4x = -1 + 25
4x = 24
x = 24 / 4
x = 6
