Simplifying x + sqrt(x + -9) = 21 Reorder the terms: x + qrst(-9 + x) = 21 x + (-9 * qrst + x * qrst) = 21 x + (-9qrst + qrstx) = 21 Reorder the terms: -9qrst + qrstx + x = 21 Solving -9qrst + qrstx + x = 21 Solving for variable 'q'. Move all terms containing q to the left, all other terms to the right. Add '-1x' to each side of the equation. -9qrst + qrstx + x + -1x = 21 + -1x Combine like terms: x + -1x = 0 -9qrst + qrstx + 0 = 21 + -1x -9qrst + qrstx = 21 + -1x Reorder the terms: -21 + -9qrst + qrstx + x = 21 + -1x + -21 + x Reorder the terms: -21 + -9qrst + qrstx + x = 21 + -21 + -1x + x Combine like terms: 21 + -21 = 0 -21 + -9qrst + qrstx + x = 0 + -1x + x -21 + -9qrst + qrstx + x = -1x + x Combine like terms: -1x + x = 0 -21 + -9qrst + qrstx + x = 0 The solution to this equation could not be determined.
