Answer:
Option A is correct.
i.e. x = 1, x = 0 is an extraneous solution.
Step-by-step explanation:
Given the expression
Solving the rational function
Apply fraction across multiply: if
Subtract x(4x+1) from both sides
Simplify
5x² - 4x² - x = 0
x² - x = 0
Factor x² - x = x(x-1)
so
x(x-1) = 0
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
Thus, the solution to the equation is:
But, it is clear that if we substitute x = 0, the equation becomes undefined because we can not have the denominator to be 0.
In other words, the equation is undefined for x = 0
Thus, x = 0 is an extraneous solutions.
Therefore, option A is correct.
i.e. x = 1, x = 0 is an extraneous solution.

Correct question
Noah drank 4/5 liter of water Monday before going jogging. He drank 2/3 liter of water after his jog. How much water did Noah drink altogether? Write your answer as a mixed number.
Answer:
Step-by-step explanation:
Noah drank 4/5 liter of water Monday before going jogging. He drank 2/3 liter of water after his jog.
To find the total liters of water he drank, we should add up the liter of water he drank on Monday before going jogging and liter of water after his jog.
4/5 + 2/3
Find the Lowest Common Multiple for 5 and 3 , which is 15.
= [(4×3) + (2×5)] /15
= 12 + 10/ 15
= 22/15
As a mixed Fraction, the answer
=
