Question

The lines represented by the pair of linear equations 3x - 10y=-4 and 5x - 4y =-3 will be____​

Answer 1

Answer:

Answer:

x+1/x = 4

Step-by-step explanation:

GIVEN:−

x = 2 + √3

1/x = 1/(2 + √3) * (2 - √3)/(2 - √3)

1/x = (2 - √3)/(4 - 3)

[ (a - b)(a + b) = (a² - b²) ]

1/x = (2 - √3)

now,

x + 1/x = (2 + √3) + (2 - √3)

x + 1/x = 2 + 2 + √3 - √3

x + 1/x = 4
