Simplifying x(a + 1) + -3(a + 1) = 0 Reorder the terms: x(1 + a) + -3(a + 1) = 0 (1 * x + a * x) + -3(a + 1) = 0 Reorder the terms: (ax + 1x) + -3(a + 1) = 0 (ax + 1x) + -3(a + 1) = 0 Reorder the terms: ax + 1x + -3(1 + a) = 0 ax + 1x + (1 * -3 + a * -3) = 0 ax + 1x + (-3 + -3a) = 0 Reorder the terms: -3 + -3a + ax + 1x = 0 Solving -3 + -3a + ax + 1x = 0 Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '3' to each side of the equation. -3 + -3a + ax + 3 + 1x = 0 + 3 Reorder the terms: -3 + 3 + -3a + ax + 1x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + -3a + ax + 1x = 0 + 3 -3a + ax + 1x = 0 + 3 Combine like terms: 0 + 3 = 3 -3a + ax + 1x = 3 Add '-1x' to each side of the equation. -3a + ax + 1x + -1x = 3 + -1x Combine like terms: 1x + -1x = 0 -3a + ax + 0 = 3 + -1x -3a + ax = 3 + -1x Reorder the terms: -3 + -3a + ax + x = 3 + -1x + -3 + x Reorder the terms: -3 + -3a + ax + x = 3 + -3 + -1x + x Combine like terms: 3 + -3 = 0 -3 + -3a + ax + x = 0 + -1x + x -3 + -3a + ax + x = -1x + x Combine like terms: -1x + x = 0 -3 + -3a + ax + x = 0 The solution to this equation could not be determined.
