Simplifying 0 = -1(-7x + 2y + -1e) + (-2x + 4y + e) Reorder the terms: 0 = -1(-1e + -7x + 2y) + (-2x + 4y + e) 0 = (-1e * -1 + -7x * -1 + 2y * -1) + (-2x + 4y + e) 0 = (1e + 7x + -2y) + (-2x + 4y + e) Reorder the terms: 0 = 1e + 7x + -2y + (e + -2x + 4y) Remove parenthesis around (e + -2x + 4y) 0 = 1e + 7x + -2y + e + -2x + 4y Reorder the terms: 0 = 1e + e + 7x + -2x + -2y + 4y Combine like terms: 1e + e = 2e 0 = 2e + 7x + -2x + -2y + 4y Combine like terms: 7x + -2x = 5x 0 = 2e + 5x + -2y + 4y Combine like terms: -2y + 4y = 2y 0 = 2e + 5x + 2y Solving 0 = 2e + 5x + 2y Solving for variable 'e'. Move all terms containing e to the left, all other terms to the right. Add '-2e' to each side of the equation. 0 + -2e = 2e + 5x + -2e + 2y Remove the zero: -2e = 2e + 5x + -2e + 2y Reorder the terms: -2e = 2e + -2e + 5x + 2y Combine like terms: 2e + -2e = 0 -2e = 0 + 5x + 2y -2e = 5x + 2y Divide each side by '-2'. e = -2.5x + -1y Simplifying e = -2.5x + -1y
