Simplifying 9(2x + -1) = 3(x + 2) * 3x Reorder the terms: 9(-1 + 2x) = 3(x + 2) * 3x (-1 * 9 + 2x * 9) = 3(x + 2) * 3x (-9 + 18x) = 3(x + 2) * 3x Reorder the terms: -9 + 18x = 3(2 + x) * 3x Reorder the terms for easier multiplication: -9 + 18x = 3 * 3x(2 + x) Multiply 3 * 3 -9 + 18x = 9x(2 + x) -9 + 18x = (2 * 9x + x * 9x) -9 + 18x = (18x + 9x2) Add '-18x' to each side of the equation. -9 + 18x + -18x = 18x + -18x + 9x2 Combine like terms: 18x + -18x = 0 -9 + 0 = 18x + -18x + 9x2 -9 = 18x + -18x + 9x2 Combine like terms: 18x + -18x = 0 -9 = 0 + 9x2 -9 = 9x2 Solving -9 = 9x2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-9x2' to each side of the equation. -9 + -9x2 = 9x2 + -9x2 Combine like terms: 9x2 + -9x2 = 0 -9 + -9x2 = 0 Add '9' to each side of the equation. -9 + 9 + -9x2 = 0 + 9 Combine like terms: -9 + 9 = 0 0 + -9x2 = 0 + 9 -9x2 = 0 + 9 Combine like terms: 0 + 9 = 9 -9x2 = 9 Divide each side by '-9'. 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.
