Simplifying f(3a) = 3a + -9 Remove parenthesis around (3a) f * 3a = 3a + -9 Reorder the terms for easier multiplication: 3f * a = 3a + -9 Multiply f * a 3af = 3a + -9 Reorder the terms: 3af = -9 + 3a Solving 3af = -9 + 3a Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-3a' to each side of the equation. -3a + 3af = -9 + 3a + -3a Combine like terms: 3a + -3a = 0 -3a + 3af = -9 + 0 -3a + 3af = -9 Reorder the terms: 9 + -3a + 3af = -9 + 9 Combine like terms: -9 + 9 = 0 9 + -3a + 3af = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(3 + -1a + af) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(3 + -1a + af)' equal to zero and attempt to solve: Simplifying 3 + -1a + af = 0 Solving 3 + -1a + af = 0 Move all terms containing a to the left, all other terms to the right. Add '-3' to each side of the equation. 3 + -1a + -3 + af = 0 + -3 Reorder the terms: 3 + -3 + -1a + af = 0 + -3 Combine like terms: 3 + -3 = 0 0 + -1a + af = 0 + -3 -1a + af = 0 + -3 Combine like terms: 0 + -3 = -3 -1a + af = -3 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
