Simplifying 7x + -49yx2 = 0 Solving 7x + -49x2y = 0 Solving for variable 'x'. Factor out the Greatest Common Factor (GCF), '7x'. 7x(1 + -7xy) = 0 Ignore the factor 7.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 + -7xy)' equal to zero and attempt to solve: Simplifying 1 + -7xy = 0 Solving 1 + -7xy = 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 + -7xy = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -7xy = 0 + -1 -7xy = 0 + -1 Combine like terms: 0 + -1 = -1 -7xy = -1 Divide each side by '-7y'. x = 0.1428571429y-1 Simplifying x = 0.1428571429y-1Solution
x = {0, 0.1428571429y-1}
