Simplifying X(7x + -3) = (7x + 8)(x + -1) Reorder the terms: X(-3 + 7x) = (7x + 8)(x + -1) (-3 * X + 7x * X) = (7x + 8)(x + -1) (-3X + 7xX) = (7x + 8)(x + -1) Reorder the terms: -3X + 7xX = (8 + 7x)(x + -1) Reorder the terms: -3X + 7xX = (8 + 7x)(-1 + x) Multiply (8 + 7x) * (-1 + x) -3X + 7xX = (8(-1 + x) + 7x * (-1 + x)) -3X + 7xX = ((-1 * 8 + x * 8) + 7x * (-1 + x)) -3X + 7xX = ((-8 + 8x) + 7x * (-1 + x)) -3X + 7xX = (-8 + 8x + (-1 * 7x + x * 7x)) -3X + 7xX = (-8 + 8x + (-7x + 7x2)) Combine like terms: 8x + -7x = 1x -3X + 7xX = (-8 + 1x + 7x2) Solving -3X + 7xX = -8 + 1x + 7x2 Solving for variable 'X'. Move all terms containing X to the left, all other terms to the right. Reorder the terms: 8 + -3X + -1x + 7xX + -7x2 = -8 + 1x + 7x2 + 8 + -1x + -7x2 Reorder the terms: 8 + -3X + -1x + 7xX + -7x2 = -8 + 8 + 1x + -1x + 7x2 + -7x2 Combine like terms: -8 + 8 = 0 8 + -3X + -1x + 7xX + -7x2 = 0 + 1x + -1x + 7x2 + -7x2 8 + -3X + -1x + 7xX + -7x2 = 1x + -1x + 7x2 + -7x2 Combine like terms: 1x + -1x = 0 8 + -3X + -1x + 7xX + -7x2 = 0 + 7x2 + -7x2 8 + -3X + -1x + 7xX + -7x2 = 7x2 + -7x2 Combine like terms: 7x2 + -7x2 = 0 8 + -3X + -1x + 7xX + -7x2 = 0 The solution to this equation could not be determined.
