Question 995450: Square root 75 plus square root 3x equals 4 rad 3

You can put this solution on YOUR website!
sqrt(75)=sqrt(25)*sqrt(3)=5 sqrt (3)
5 sqrt (3)+sqrt (3x)=4 sqrt(3)
subtract 5 sqrt (3) from both sides
sqrt(3x)= -sqrt (3)
square both sides
3x= (-3)
x=-1
==========
Check to see if this is possible.
5 sqrt(3) + sqrt (-3)=4 sqrt (3)
sqrt (-3) does not exist in real system.
no solution.
