Simplifying 7x + -1(4x + -1) = 2 Reorder the terms: 7x + -1(-1 + 4x) = 2 7x + (-1 * -1 + 4x * -1) = 2 7x + (1 + -4x) = 2 Reorder the terms: 1 + 7x + -4x = 2 Combine like terms: 7x + -4x = 3x 1 + 3x = 2 Solving 1 + 3x = 2 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + 3x = 2 + -1 Combine like terms: 1 + -1 = 0 0 + 3x = 2 + -1 3x = 2 + -1 Combine like terms: 2 + -1 = 1 3x = 1 Divide each side by '3'. x = 0.3333333333 Simplifying x = 0.3333333333
