Question

Given these equations , find x and y

Answer 1

Step-by-step explanation:

we have given

x + y = 6 --------------------------(1)

xy = 8 ----------------------------(2)

from (1)

x = 6 - y, put this value of x in equation (2)

( 6 - y) y = 8

6y - y^2 - 8 = 0

multiply ( - 1 ) on both the sides

- 6 y + y² + 8 = 0

y² - 6y + 8 = 0

y² - 4y - 2y + 8 = 0

y ( y - 4 ) - 2 ( y - 4 ) = 0

( y - 2 ) ( y - 4) = 0

y = 2 or y = 4

therefor put the values of y in equation ( 1) , then we can get the values of x

x + y = 6

x + 2 = 6 Or x + 4 = 6

x = 6 - 2 or x = 6 - 4

x = 4 or x = 2

Therefor the values of x and y are

$\boxed{\textbf{\large{ x = 4 or 2 And y = 2 or 4}}}$

Answer 2

Answer:

x- 4/2 or y-4/2
