The values of x and y are x = √-7/150 and y = 10√-7/150, respectively
How to determine the solution to the equations
From the question, we have the following parameters that can be used in our computation:
y = 2x * 5
5x * 3y = -7
When evaluated, we have
y = 10x
5x * 3y = -7
Substitute the known values into the equation
5x * 3 * 10x = -7
150x² = -7
So, we have
x = √-7/150
Recall that
y = 10x
So, we have
y = 10√-7/150
hence, the values of x and y are x = √-7/150 and y = 10√-7/150, respectively
