Simplifying 3a + -2(a + 7) = a + 1 Reorder the terms: 3a + -2(7 + a) = a + 1 3a + (7 * -2 + a * -2) = a + 1 3a + (-14 + -2a) = a + 1 Reorder the terms: -14 + 3a + -2a = a + 1 Combine like terms: 3a + -2a = 1a -14 + 1a = a + 1 Reorder the terms: -14 + 1a = 1 + a Solving -14 + 1a = 1 + a Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-1a' to each side of the equation. -14 + 1a + -1a = 1 + a + -1a Combine like terms: 1a + -1a = 0 -14 + 0 = 1 + a + -1a -14 = 1 + a + -1a Combine like terms: a + -1a = 0 -14 = 1 + 0 -14 = 1 Add '14' to each side of the equation. -14 + 14 = 1 + 14 Combine like terms: -14 + 14 = 0 0 = 1 + 14 Combine like terms: 1 + 14 = 15 0 = 15 Simplifying 0 = 15 Combine like terms: 0 + -15 = -15 -15 = 15 + -15 Combine like terms: 15 + -15 = 0 -15 = 0 The solution to this equation could not be determined.
