SOLUTION: I was wondering for equation,sqrt(3y+7)= y+1, y =-2&3 -2 because you would get sqrt(3(-2)+7)=-2+1 ==>sqrt (1)=-1, and this works because sqrt 1= -1^2 So would -2 be one of the so

Question 762284: I was wondering for equation,sqrt(3y+7)= y+1, y =-2&3
-2 because you would get sqrt(3(-2)+7)=-2+1 ==>sqrt (1)=-1, and this works because sqrt 1= -1^2
So would -2 be one of the solutions?
