Simplifying 0 = 2x3 + 2X2 + -18x + -18 Reorder the terms: 0 = -18 + 2X2 + -18x + 2x3 Solving 0 = -18 + 2X2 + -18x + 2x3 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Add '-2X2' to each side of the equation. 0 + -2X2 = -18 + 2X2 + -18x + -2X2 + 2x3 Remove the zero: -2X2 = -18 + 2X2 + -18x + -2X2 + 2x3 Reorder the terms: -2X2 = -18 + 2X2 + -2X2 + -18x + 2x3 Combine like terms: 2X2 + -2X2 = 0 -2X2 = -18 + 0 + -18x + 2x3 -2X2 = -18 + -18x + 2x3 Divide each side by '-2'. X2 = 9 + 9x + -1x3 Simplifying X2 = 9 + 9x + -1x3 Reorder the terms: -9 + X2 + -9x + x3 = 9 + 9x + -1x3 + -9 + -9x + x3 Reorder the terms: -9 + X2 + -9x + x3 = 9 + -9 + 9x + -9x + -1x3 + x3 Combine like terms: 9 + -9 = 0 -9 + X2 + -9x + x3 = 0 + 9x + -9x + -1x3 + x3 -9 + X2 + -9x + x3 = 9x + -9x + -1x3 + x3 Combine like terms: 9x + -9x = 0 -9 + X2 + -9x + x3 = 0 + -1x3 + x3 -9 + X2 + -9x + x3 = -1x3 + x3 Combine like terms: -1x3 + x3 = 0 -9 + X2 + -9x + x3 = 0 The solution to this equation could not be determined.
