Simplifying 3 (5 + - 1e) + 2 = 10 (5 * 3 + - 1e * 3) + 2 = 10 (15 + - 3e) + 2 = 10 Reorder the terms: 15 + 2 + - 3e = 10 Combine like terms: 15 + 2 = 17 17 + - 3e = 10 Solving 17 + - 3e = 10 Solving for variable 'e'. Move all terms containing e to the left, all other terms to the right. Add '-17' to each side of the equation. 17 + - 17 + - 3e = 10 + - 17 Combine like terms: 17 + - 17 = 0 0 + - 3e = 10 + - 17 - 3e = 10 + - 17 Combine like terms: 10 + - 17 = - 7 - 3e = - 7 Divide each side by '-3'. e = 2.333333333 Simplifying e = 2.333333333
