Solution for (4+V)(5V-1)=0 equation:


Simplifying
(4 + V)(5V + -1) = 0

Reorder the terms:
(4 + V)(-1 + 5V) = 0

Multiply (4 + V) * (-1 + 5V)
(4(-1 + 5V) + V(-1 + 5V)) = 0
((-1 * 4 + 5V * 4) + V(-1 + 5V)) = 0
((-4 + 20V) + V(-1 + 5V)) = 0
(-4 + 20V + (-1 * V + 5V * V)) = 0
(-4 + 20V + (-1V + 5V2)) = 0

Combine like terms: 20V + -1V = 19V
(-4 + 19V + 5V2) = 0

Solving
-4 + 19V + 5V2 = 0

Solving for variable 'V'.
