Solve 2/5x + 4 = 1/5

Answer 1

To solve the equation 2/5x + 4 = 1/5, we need to isolate x.

First, let's get rid of the 4 on the left side by subtracting 4 from both sides of the equation:

2/5x + 4 - 4 = 1/5 - 4
2/5x = 1/5 - 20/5

Simplifying the right side:

2/5x = (1 - 20)/5
2/5x = -19/5

Now, to isolate x, we need to divide both sides by 2/5:

(2/5x) / (2/5) = (-19/5) / (2/5)
x = -19/5 * 5/2

Simplifying the right side:

x = -19/2

Therefore, the solution to the equation 2/5x + 4 = 1/5 is x = -19/2.
