Question

if x-y=5 and xy=24 , find the value of x+y .

Answer 1

Answer:

x=8, y=3, x+y=11

Step-by-step explanation:

x-y=5

xy=24

y=24/x

x-24/x=5

x^2-24/x=5

x^2-5x-24=0

x=8 or -3(factorisation)

if we substitute (-3) in both equations,

-3 dosent satisfy both the equation .

but(8)satisfies both the equation when y is equal to 3.

hence x= 8,y=3

x+y=11
