Simplifying 6(x + 1) + 5 = 13 + -2 + 6x Reorder the terms: 6(1 + x) + 5 = 13 + -2 + 6x (1 * 6 + x * 6) + 5 = 13 + -2 + 6x (6 + 6x) + 5 = 13 + -2 + 6x Reorder the terms: 6 + 5 + 6x = 13 + -2 + 6x Combine like terms: 6 + 5 = 11 11 + 6x = 13 + -2 + 6x Combine like terms: 13 + -2 = 11 11 + 6x = 11 + 6x Add '-11' to each side of the equation. 11 + -11 + 6x = 11 + -11 + 6x Combine like terms: 11 + -11 = 0 0 + 6x = 11 + -11 + 6x 6x = 11 + -11 + 6x Combine like terms: 11 + -11 = 0 6x = 0 + 6x 6x = 6x Add '-6x' to each side of the equation. 6x + -6x = 6x + -6x Combine like terms: 6x + -6x = 0 0 = 6x + -6x Combine like terms: 6x + -6x = 0 0 = 0 Solving 0 = 0 Couldn't find a variable to solve for. This equation is an identity, all real numbers are solutions.
