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 = 0Subproblem 2
Set the factor '(2x + 7a)' equal to zero and attempt to solve: Simplifying 2x + 7a = 0 Reorder the terms: 7a + 2x = 0 Solving 7a + 2x = 0 Move all terms containing a to the left, all other terms to the right. Add '-2x' to each side of the equation. 7a + 2x + -2x = 0 + -2x Combine like terms: 2x + -2x = 0 7a + 0 = 0 + -2x 7a = 0 + -2x Remove the zero: 7a = -2x Divide each side by '7'. a = -0.2857142857x Simplifying a = -0.2857142857xSolution
a = {0, -0.2857142857x}
