Question

Find a number which when increased by 4 is equal to 12 times the reciprocal of the number

Answer 1

Answer:

The number is 8.

Answer 2

Step-by-step explanation:

let the no. be x

x+4 = 12/x

sending x to LHS,

x square + 4x -12 = 0

splitting 4x and taking common,

x square +6x -2x -12 = 0

x(x+6) -2(x+6)= 0

(x-6)(x-2)=0

therefore x= 2 or x = -6
