Subproblem 1

Set the factor '(-2u + -1z)' equal to zero and attempt to solve: Simplifying -2u + -1z = 0 Solving -2u + -1z = 0 Move all terms containing u to the left, all other terms to the right. Add 'z' to each side of the equation. -2u + -1z + z = 0 + z Combine like terms: -1z + z = 0 -2u + 0 = 0 + z -2u = 0 + z Remove the zero: -2u = z Divide each side by '-2'. u = -0.5z Simplifying u = -0.5z

Subproblem 2

Set the factor '(u + -9z)' equal to zero and attempt to solve: Simplifying u + -9z = 0 Solving u + -9z = 0 Move all terms containing u to the left, all other terms to the right. Add '9z' to each side of the equation. u + -9z + 9z = 0 + 9z Combine like terms: -9z + 9z = 0 u + 0 = 0 + 9z u = 0 + 9z Remove the zero: u = 9z Simplifying u = 9z

Solution

u = {-0.5z, 9z}
