160+100+180+60=500
180/500=0.36=36%
50x36%=18
That's your answer lovely~
Consider the equation:
Subtracting '4' from both the sides of the equation, we get as
Squaring on both the sides of the equation, we get
Subtracting '2' from both the sides of the equation, we get
x=14
Since, An extraneous solution is a solution that arises from the solving process that is not really a solution at all. But, in this equation x=14 is the solution of the given equation.
Hence, it is not an extraneous solution.
If you don’t your answer will not be correct also when you use them it helps you find the correct answer
It’s the one that is marked as (3,3)
