Let’s check out your problem:

sqrt(y-1)+3=y

y1+3=y \sqrt{y-1}+3=y

Full solution

Q. y1+3=y \sqrt{y-1}+3=y
  1. Isolate square root: Isolate the square root by subtracting 33 from both sides of the equation.\newliney1=y3\sqrt{y-1} = y - 3
  2. Square both sides: Square both sides to eliminate the square root. y - \(1) = (y - 33)^22\
  3. Expand right side: Expand the right side of the equation. y - \(1) = y^22 - 66y + 99\
  4. Move terms to one side: Move all terms to one side to set the equation to zero.\newline0=y26y+y9+10 = y^2 - 6y + y - 9 + 1
  5. Combine like terms: Combine like terms.\newline0=y25y80 = y^2 - 5y - 8
  6. Factor quadratic equation: Factor the quadratic equation.\newline0=(y8)(y+1)0 = (y - 8)(y + 1)
  7. Set factors equal: Set each factor equal to zero and solve for yy.y8=0y - 8 = 0 or y+1=0y + 1 = 0y=8y = 8 or y=1y = -1
