To find the solution of the equation 2/5 * x + 4 = 1/5, we need to isolate the variable x.
First, subtract 4 from both sides of the equation:
2/5 * x + 4 - 4 = 1/5 - 4
2/5 * x = 1/5 - 20/5
2/5 * x = -19/5
To solve for x, multiply both sides of the equation by the reciprocal of 2/5 (which is 5/2):
(5/2) * (2/5) * x = (5/2) * (-19/5)
x = -19/2
Therefore, the solution to the equation is -19/2.
