Simplifying 2(x2 + -1) = (x2 + -3) Reorder the terms: 2(-1 + x2) = (x2 + -3) (-1 * 2 + x2 * 2) = (x2 + -3) (-2 + 2x2) = (x2 + -3) Reorder the terms: -2 + 2x2 = (-3 + x2) Remove parenthesis around (-3 + x2) -2 + 2x2 = -3 + x2 Solving -2 + 2x2 = -3 + x2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1x2' to each side of the equation. -2 + 2x2 + -1x2 = -3 + x2 + -1x2 Combine like terms: 2x2 + -1x2 = 1x2 -2 + 1x2 = -3 + x2 + -1x2 Combine like terms: x2 + -1x2 = 0 -2 + 1x2 = -3 + 0 -2 + 1x2 = -3 Add '2' to each side of the equation. -2 + 2 + 1x2 = -3 + 2 Combine like terms: -2 + 2 = 0 0 + 1x2 = -3 + 2 1x2 = -3 + 2 Combine like terms: -3 + 2 = -1 1x2 = -1 Divide each side by '1'. x2 = -1 Simplifying x2 = -1 Reorder the terms: 1 + x2 = -1 + 1 Combine like terms: -1 + 1 = 0 1 + x2 = 0 The solution to this equation could not be determined.
