Subproblem 1

Set the factor '(31 + -1w)' equal to zero and attempt to solve: Simplifying 31 + -1w = 0 Solving 31 + -1w = 0 Move all terms containing w to the left, all other terms to the right. Add '-31' to each side of the equation. 31 + -31 + -1w = 0 + -31 Combine like terms: 31 + -31 = 0 0 + -1w = 0 + -31 -1w = 0 + -31 Combine like terms: 0 + -31 = -31 -1w = -31 Divide each side by '-1'. w = 31 Simplifying w = 31

Subproblem 2

Set the factor '(35 + w)' equal to zero and attempt to solve: Simplifying 35 + w = 0 Solving 35 + w = 0 Move all terms containing w to the left, all other terms to the right. Add '-35' to each side of the equation. 35 + -35 + w = 0 + -35 Combine like terms: 35 + -35 = 0 0 + w = 0 + -35 w = 0 + -35 Combine like terms: 0 + -35 = -35 w = -35 Simplifying w = -35

Solution

w = {31, -35}
