Subproblem 1

Set the factor '(s + t)' equal to zero and attempt to solve: Simplifying s + t = 0 Solving s + t = 0 Move all terms containing s to the left, all other terms to the right. Add '-1t' to each side of the equation. s + t + -1t = 0 + -1t Combine like terms: t + -1t = 0 s + 0 = 0 + -1t s = 0 + -1t Remove the zero: s = -1t Simplifying s = -1t

Subproblem 2

Set the factor '(9s + 11t)' equal to zero and attempt to solve: Simplifying 9s + 11t = 0 Solving 9s + 11t = 0 Move all terms containing s to the left, all other terms to the right. Add '-11t' to each side of the equation. 9s + 11t + -11t = 0 + -11t Combine like terms: 11t + -11t = 0 9s + 0 = 0 + -11t 9s = 0 + -11t Remove the zero: 9s = -11t Divide each side by '9'. s = -1.222222222t Simplifying s = -1.222222222t

Solution

s = {-1t, -1.222222222t}
