Simplifying 3X = 21X2 Solving 3X = 21X2 Solving for variable 'X'. Combine like terms: 21X2 + -21X2 = 0 3X + -21X2 = 0 Factor out the Greatest Common Factor (GCF), '3X'. 3X(1 + -7X) = 0 Ignore the factor 3.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 = 0Subproblem 2
Set the factor '(1 + -7X)' equal to zero and attempt to solve: Simplifying 1 + -7X = 0 Solving 1 + -7X = 0 Move all terms containing X to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -7X = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -7X = 0 + -1 -7X = 0 + -1 Combine like terms: 0 + -1 = -1 -7X = -1 Divide each side by '-7'. X = 0.1428571429 Simplifying X = 0.1428571429Solution
X = {0, 0.1428571429}
