Simplifying 7(7x + 4) = 49x Reorder the terms: 7(4 + 7x) = 49x (4 * 7 + 7x * 7) = 49x (28 + 49x) = 49x Add '-49x' to each side of the equation. 28 + 49x + -49x = 49x + -49x Combine like terms: 49x + -49x = 0 28 + 0 = 49x + -49x 28 = 49x + -49x Combine like terms: 49x + -49x = 0 28 = 0 Solving 28 = 0 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.
