Subproblem 1

Set the factor '(w + -3x)' equal to zero and attempt to solve: Simplifying w + -3x = 0 Solving w + -3x = 0 Move all terms containing w to the left, all other terms to the right. Add '3x' to each side of the equation. w + -3x + 3x = 0 + 3x Combine like terms: -3x + 3x = 0 w + 0 = 0 + 3x w = 0 + 3x Remove the zero: w = 3x Simplifying w = 3x

Subproblem 2

Set the factor '(3w + -7x)' equal to zero and attempt to solve: Simplifying 3w + -7x = 0 Solving 3w + -7x = 0 Move all terms containing w to the left, all other terms to the right. Add '7x' to each side of the equation. 3w + -7x + 7x = 0 + 7x Combine like terms: -7x + 7x = 0 3w + 0 = 0 + 7x 3w = 0 + 7x Remove the zero: 3w = 7x Divide each side by '3'. w = 2.333333333x Simplifying w = 2.333333333x

Solution

w = {3x, 2.333333333x}
