Simplifying 2x + -1(6 + -1x) + 4x + 6 = 7x + 2 2x + (6 * -1 + -1x * -1) + 4x + 6 = 7x + 2 2x + (-6 + 1x) + 4x + 6 = 7x + 2 Reorder the terms: -6 + 6 + 2x + 1x + 4x = 7x + 2 Combine like terms: -6 + 6 = 0 0 + 2x + 1x + 4x = 7x + 2 2x + 1x + 4x = 7x + 2 Combine like terms: 2x + 1x = 3x 3x + 4x = 7x + 2 Combine like terms: 3x + 4x = 7x 7x = 7x + 2 Reorder the terms: 7x = 2 + 7x Add '-7x' to each side of the equation. 7x + -7x = 2 + 7x + -7x Combine like terms: 7x + -7x = 0 0 = 2 + 7x + -7x Combine like terms: 7x + -7x = 0 0 = 2 + 0 0 = 2 Solving 0 = 2 Couldn't find a variable to solve for. This equation is invalid, the left and right sides are not equal, therefore there is no solution.
