To solve the equation 2/5x + 4 = 1/5, we first need to isolate x by getting rid of the constant term on the left side of the equation.
Subtracting 4 from both sides, we get:
2/5x = 1/5 - 4
Simplifying the right side:
2/5x = 1/5 - 20/5
2/5x = -19/5
Next, we need to multiply both sides of the equation by the reciprocal of 2/5 (which is 5/2) to solve for x:
(5/2)(2/5)x = (5/2)(-19/5)
Canceling out the common factors:
(1)x = -19/2
Therefore, the solution to the equation is:
x = -19/2 or -9.5
2/5x +4= 1/5
