Question

sum of the two no is 5.1 .if one of the no exced the other no by11 then find the product of the two numbers?

Answer 1

Answer:

-23.75

Step-by-step explanation:

x+y=5.1 .......(1)

x-y=11 ..........(2)

equation (1) +(2),     x + y + x - y = 5.1 + 11

                               ⇒ 2x = 16.1 ⇒ x = 8.05

    and x - y = 11 ⇒ y = x - 11 = 8.05 - 11 = -2.95

product of x and y = 8.05 X -2.95 = -23.75
