Simplifying a2x + -7a3 = 0 Solving a2x + -7a3 = 0 Solving for variable 'a'. Factor out the Greatest Common Factor (GCF), 'a2'. a2(x + -7a) = 0Subproblem 1
Set the factor 'a2' equal to zero and attempt to solve: Simplifying a2 = 0 Solving a2 = 0 Move all terms containing a to the left, all other terms to the right. Simplifying a2 = 0 Take the square root of each side: a = {0}Subproblem 2
Set the factor '(x + -7a)' equal to zero and attempt to solve: Simplifying x + -7a = 0 Reorder the terms: -7a + x = 0 Solving -7a + x = 0 Move all terms containing a to the left, all other terms to the right. Add '-1x' to each side of the equation. -7a + x + -1x = 0 + -1x Combine like terms: x + -1x = 0 -7a + 0 = 0 + -1x -7a = 0 + -1x Remove the zero: -7a = -1x Divide each side by '-7'. a = 0.1428571429x Simplifying a = 0.1428571429xSolution
a = {0, 0.1428571429x}
