Simplifying 3b + -7 = 3(b + 1) Reorder the terms: -7 + 3b = 3(b + 1) Reorder the terms: -7 + 3b = 3(1 + b) -7 + 3b = (1 * 3 + b * 3) -7 + 3b = (3 + 3b) Add '-3b' to each side of the equation. -7 + 3b + -3b = 3 + 3b + -3b Combine like terms: 3b + -3b = 0 -7 + 0 = 3 + 3b + -3b -7 = 3 + 3b + -3b Combine like terms: 3b + -3b = 0 -7 = 3 + 0 -7 = 3 Solving -7 = 3 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.
