1.57i check out the workings.

Mark me as brainiest. Thanks!

Step-by-step explanation:

xy = 96

x-y = -40

xy = 96

y(x-y = -40y)

xy = 96

xy - y^2 = -40y^2

xy = 96

xy = -40y^2 + y^2

xy = 96

xy = -39y^2

96 = -39y^2  (divide by co-efficient of y^2)

-2.4615384615385 = y^2

y = 1.56892908 i approx. 1.57i  (i is an imaginary number in math.)
