Simplifying 5x + -7(x + -1) = ax + b Reorder the terms: 5x + -7(-1 + x) = ax + b 5x + (-1 * -7 + x * -7) = ax + b 5x + (7 + -7x) = ax + b Reorder the terms: 7 + 5x + -7x = ax + b Combine like terms: 5x + -7x = -2x 7 + -2x = ax + b Solving 7 + -2x = ax + b Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-1ax' to each side of the equation. 7 + -1ax + -2x = ax + -1ax + b Combine like terms: ax + -1ax = 0 7 + -1ax + -2x = 0 + b 7 + -1ax + -2x = b Add '-7' to each side of the equation. 7 + -1ax + -7 + -2x = -7 + b Reorder the terms: 7 + -7 + -1ax + -2x = -7 + b Combine like terms: 7 + -7 = 0 0 + -1ax + -2x = -7 + b -1ax + -2x = -7 + b Reorder the terms: 7 + -1ax + -1b + -2x = -7 + b + 7 + -1b Reorder the terms: 7 + -1ax + -1b + -2x = -7 + 7 + b + -1b Combine like terms: -7 + 7 = 0 7 + -1ax + -1b + -2x = 0 + b + -1b 7 + -1ax + -1b + -2x = b + -1b Combine like terms: b + -1b = 0 7 + -1ax + -1b + -2x = 0 The solution to this equation could not be determined.
