Move all terms containing x to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + x3 = 7 + 1 Combine like terms: -1 + 1 = 0 0 + x3 = 7 + 1 x3 = 7 + 1 Combine like terms: 7 + 1 = 8 x3 = 8 Simplifying x3 = 8 Reorder the terms: -8 + x3 = 8 + -8 Combine like terms: 8 + -8 = 0 -8 + x3 = 0 The solution to this equation could not be determined.
