Subproblem 1

Set the factor 'a' equal to zero and attempt to solve: Simplifying a = 0 Solving a = 0 Move all terms containing a to the left, all other terms to the right. Simplifying a = 0

Subproblem 2

Set the factor '(x + -3a)' equal to zero and attempt to solve: Simplifying x + -3a = 0 Reorder the terms: -3a + x = 0 Solving -3a + x = 0 Move all terms containing a to the left, all other terms to the right. Add '-1x' to each side of the equation. -3a + x + -1x = 0 + -1x Combine like terms: x + -1x = 0 -3a + 0 = 0 + -1x -3a = 0 + -1x Remove the zero: -3a = -1x Divide each side by '-3'. a = 0.3333333333x Simplifying a = 0.3333333333x

Solution

a = {0, 0.3333333333x}
