Simplifying 2(2b + -5) = 4(b + -2) Reorder the terms: 2(-5 + 2b) = 4(b + -2) (-5 * 2 + 2b * 2) = 4(b + -2) (-10 + 4b) = 4(b + -2) Reorder the terms: -10 + 4b = 4(-2 + b) -10 + 4b = (-2 * 4 + b * 4) -10 + 4b = (-8 + 4b) Add '-4b' to each side of the equation. -10 + 4b + -4b = -8 + 4b + -4b Combine like terms: 4b + -4b = 0 -10 + 0 = -8 + 4b + -4b -10 = -8 + 4b + -4b Combine like terms: 4b + -4b = 0 -10 = -8 + 0 -10 = -8 Solving -10 = -8 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.
