Question

3x+3/x=1 then find x^3+3/x^3+1=?​

Answer 1

Answer:

3/19

Step-by-step explanation:

Since:3x+3/x = 1

Therefore: x = 3x + 3 (cross multiplication)

Therefore: 3x-x = -3 (by getting the same values on one side)

Therefore: 2x = -3

Therefore: X= -3/2

By substituting in the second equation:

(-3/2)^3 + 3 / (-3/2)^3 + 1 = 3/19
