If it's not what You are looking for type in the equation solver your own equation and let us solve it.

Simplifying -9 = -1u Solving -9 = -1u Solving for variable 'u'. Move all terms containing u to the left, all other terms to the right. Add 'u' to each side of the equation. -9 + u = -1u + u Combine like terms: -1u + u = 0 -9 + u = 0 Add '9' to each side of the equation. -9 + 9 + u = 0 + 9 Combine like terms: -9 + 9 = 0 0 + u = 0 + 9 u = 0 + 9 Combine like terms: 0 + 9 = 9 u = 9 Simplifying u = 9
