Simplifying X2 + y2 + 2y + 4 = 25 Reorder the terms: 4 + X2 + 2y + y2 = 25 Solving 4 + X2 + 2y + y2 = 25 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + X2 + 2y + -4 + y2 = 25 + -4 Reorder the terms: 4 + -4 + X2 + 2y + y2 = 25 + -4 Combine like terms: 4 + -4 = 0 0 + X2 + 2y + y2 = 25 + -4 X2 + 2y + y2 = 25 + -4 Combine like terms: 25 + -4 = 21 X2 + 2y + y2 = 21 Add '-2y' to each side of the equation. X2 + 2y + -2y + y2 = 21 + -2y Combine like terms: 2y + -2y = 0 X2 + 0 + y2 = 21 + -2y X2 + y2 = 21 + -2y Add '-1y2' to each side of the equation. X2 + y2 + -1y2 = 21 + -2y + -1y2 Combine like terms: y2 + -1y2 = 0 X2 + 0 = 21 + -2y + -1y2 X2 = 21 + -2y + -1y2 Simplifying X2 = 21 + -2y + -1y2 Reorder the terms: -21 + X2 + 2y + y2 = 21 + -2y + -1y2 + -21 + 2y + y2 Reorder the terms: -21 + X2 + 2y + y2 = 21 + -21 + -2y + 2y + -1y2 + y2 Combine like terms: 21 + -21 = 0 -21 + X2 + 2y + y2 = 0 + -2y + 2y + -1y2 + y2 -21 + X2 + 2y + y2 = -2y + 2y + -1y2 + y2 Combine like terms: -2y + 2y = 0 -21 + X2 + 2y + y2 = 0 + -1y2 + y2 -21 + X2 + 2y + y2 = -1y2 + y2 Combine like terms: -1y2 + y2 = 0 -21 + X2 + 2y + y2 = 0 The solution to this equation could not be determined.
