Solving for variable 'x'.

Factor out the Greatest Common Factor (GCF), '-1x'.
-1x(26 + 7x) = 0

Ignore the factor -1.

Subproblem 1

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

Subproblem 2

Set the factor '(26 + 7x)' equal to zero and attempt to solve: Simplifying 26 + 7x = 0 Solving 26 + 7x = 0 Move all terms containing x to the left, all other terms to the right. Add '-26' to each side of the equation. 26 + -26 + 7x = 0 + -26 Combine like terms: 26 + -26 = 0 0 + 7x = 0 + -26 7x = 0 + -26 Combine like terms: 0 + -26 = -26 7x = -26 Divide each side by '7'. x = -3.714285714 Simplifying x = -3.714285714

Solution

x = {0, -3.714285714}
