Simplifying -4b + 1 = -4(b + 7) Reorder the terms: 1 + -4b = -4(b + 7) Reorder the terms: 1 + -4b = -4(7 + b) 1 + -4b = (7 * -4 + b * -4) 1 + -4b = (-28 + -4b) Add '4b' to each side of the equation. 1 + -4b + 4b = -28 + -4b + 4b Combine like terms: -4b + 4b = 0 1 + 0 = -28 + -4b + 4b 1 = -28 + -4b + 4b Combine like terms: -4b + 4b = 0 1 = -28 + 0 1 = -28 Solving 1 = -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.
