Expert Answer:

x/2+y=0.8   ..................(1)

7/x+y=10    .................(2)

Subtrating (1) from (2)

7/x - x/2 = 9.2

On solving the above equation would reduce to a quadratic equation x2 + 18.4x -14 = 0

Here b2 - 4ac < 0, therefore the above equation has imaginary roots which can be obtained by using the formula

x = (-b b2 -4ac) / 2a
