x+y+xy=41,x+z+xz=26,y+z+yz=125. find x,y,z.

who will give me correct information their answer will be marked as branilist answer​

Answer 1

Step-by-step explanation:

x + ʏ = xʏ = 41 ,x + ᴢ + xᴢ = 26 , ʏ + ᴢ + ʏᴢ = 125

41 × 26

= 1,040

= 1,040 ÷ 125

= 8.32

Answer 2

Step-by-step explanation:

−50y+(50−2y)(y+1)

=41

⇒621+y

2

−50y+50y−50−2y

2

−

+2y−15=0

⇒y

2

−3y+5y−15=0

⇒y(y−3)+5(y−3)=0

⇒(y+5)(y−3)=0

⇒y=−5,3

Substituting y in (i), we get

⇒x=−7,5

Substituting y in (ii), we get

⇒z=−8,6
