Question

X + y is equals to 36 x into y is equals to 248 what is x and y

Answer 1

Answer:

Step-by-step explanation:

Given: x + y = 5 ………….( 1 ) and

xy = 6

=> y = 6/x ,…………(2)

Put value of “y” in equation (1), we get

x +6/x = 5

=> (x.x+ 6)/x = 5

=> (x^2+ 6)/x = 5

=>x^2+ 6 = 5x

=>x^2 -5x+ 6 = 0

=>x^2 -3x -2x+ 6 = 0

=>x(x -3) - 2( x-3) = 0

=> (x -2) ( x-3) = 0

=> x -2= 0 or x-3 = 0

=> x = 2 or x= 3

Put x = 2 in equation (2), we get

y = 6/2 = 3

Put x = 3 in equation (2), we get

y = 6/3 = 2

Check: Put x= 2 and y =3 in equation (1), we get

2 + 3 = 5

=>5 = 5 …………….Proved

Therefore; x = 2 or 3 and

y = 3 or 2 ……………………Answer
