Simplifying 4(x + -2) + 6 = 4x + 7 Reorder the terms: 4(-2 + x) + 6 = 4x + 7 (-2 * 4 + x * 4) + 6 = 4x + 7 (-8 + 4x) + 6 = 4x + 7 Reorder the terms: -8 + 6 + 4x = 4x + 7 Combine like terms: -8 + 6 = -2 -2 + 4x = 4x + 7 Reorder the terms: -2 + 4x = 7 + 4x Add '-4x' to each side of the equation. -2 + 4x + -4x = 7 + 4x + -4x Combine like terms: 4x + -4x = 0 -2 + 0 = 7 + 4x + -4x -2 = 7 + 4x + -4x Combine like terms: 4x + -4x = 0 -2 = 7 + 0 -2 = 7 Solving -2 = 7 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.
