Simplifying u + 83 = 7(5 + -1u) + 8u + -7 Reorder the terms: 83 + u = 7(5 + -1u) + 8u + -7 83 + u = (5 * 7 + -1u * 7) + 8u + -7 83 + u = (35 + -7u) + 8u + -7 Reorder the terms: 83 + u = 35 + -7 + -7u + 8u Combine like terms: 35 + -7 = 28 83 + u = 28 + -7u + 8u Combine like terms: -7u + 8u = 1u 83 + u = 28 + 1u Solving 83 + u = 28 + 1u Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add '-1u' to each side of the equation. 83 + u + -1u = 28 + 1u + -1u Combine like terms: u + -1u = 0 83 + 0 = 28 + 1u + -1u 83 = 28 + 1u + -1u Combine like terms: 1u + -1u = 0 83 = 28 + 0 83 = 28 Add '-83' to each side of the equation. 83 + -83 = 28 + -83 Combine like terms: 83 + -83 = 0 0 = 28 + -83 Combine like terms: 28 + -83 = -55 0 = -55 Simplifying 0 = -55 Combine like terms: 0 + 55 = 55 55 = -55 + 55 Combine like terms: -55 + 55 = 0 55 = 0 The solution to this equation could not be determined.
