Question

${1 {5516222.}^{?} }^{?155201 \times \frac{?}{?} }$
​

Answer 1

Answer:

Step-by-step explanation:

x+y=-4

x=-4-y (call this equation 1)

also xy=2

y=2/x (call this equation 2)

since x =-4-y thus usimg this value of x in equation 2 , we get

y=2/-4-y

-4y-y^2=2 ( cross multiplication)

-y^2-4y=2

or y^2+4y=-2

y^2+4y+2=O

after solving this quad. equation get value of y n then using this value of y get value of x usimg equation 1 then put on this value of x n y in given problem n get the answer ; )
