Simplifying 686z + -2z7 = 0 Solving 686z + -2z7 = 0 Solving for variable 'z'. Factor out the Greatest Common Factor (GCF), '2z'. 2z(343 + -1z6) = 0 Ignore the factor 2.Subproblem 1
Set the factor 'z' equal to zero and attempt to solve: Simplifying z = 0 Solving z = 0 Move all terms containing z to the left, all other terms to the right. Simplifying z = 0Subproblem 2
Set the factor '(343 + -1z6)' equal to zero and attempt to solve: Simplifying 343 + -1z6 = 0 Solving 343 + -1z6 = 0 Move all terms containing z to the left, all other terms to the right. Add '-343' to each side of the equation. 343 + -343 + -1z6 = 0 + -343 Combine like terms: 343 + -343 = 0 0 + -1z6 = 0 + -343 -1z6 = 0 + -343 Combine like terms: 0 + -343 = -343 -1z6 = -343 Divide each side by '-1'. z6 = 343 Simplifying z6 = 343 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Solution
