Solution for (-4z^2-11u)-5z^2=
Simplifying (-4z2 + -11u) + -5z2 = 0
Reorder the terms: (-11u + -4z2) + -5z2 = 0
Remove parenthesis around (-11u + -4z2) -11u + -4z2 + -5z2 = 0
Combine like terms: -4z2 + -5z2 = -9z2 -11u + -9z2 = 0 Solving -11u + -9z2 = 0 Solving for variable 'u'.
Add '9z2' to each side of the equation. -11u + -9z2 + 9z2 = 0 + 9z2 Combine like terms: -9z2 + 9z2 = 0 -11u + 0 = 0 + 9z2 -11u = 0 + 9z2
Remove the zero: -11u = 9z2 Divide each side by '-11'. u = -0.8181818182z2 Simplifying u = -0.8181818182z
