sqaure root of x+3 = sqaure root of 2x-7
Answer by checkley77(12844) (Show Source): You can put this solution on YOUR website!
sqaure root of x+3 = sqaure root of 2x-7
sqrt(x+3)=sqrt(2x-7)squaring both sides we get:
x+3=2x-7
x-2x=-7-3
-x=-10
x=10 answer.
Proof:
sqrt(10+3)=sqrt(2*10-7)
sqrt13=sqrt(20-7)
sqrt13=sqrt13
