Simplifying 4x + 5 = 4(x + 7) Reorder the terms: 5 + 4x = 4(x + 7) Reorder the terms: 5 + 4x = 4(7 + x) 5 + 4x = (7 * 4 + x * 4) 5 + 4x = (28 + 4x) Add '-4x' to each side of the equation. 5 + 4x + -4x = 28 + 4x + -4x Combine like terms: 4x + -4x = 0 5 + 0 = 28 + 4x + -4x 5 = 28 + 4x + -4x Combine like terms: 4x + -4x = 0 5 = 28 + 0 5 = 28 Solving 5 = 28 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.
