What is the solution of the equation?2/5x + 4 = 1/5

Answer 1

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

First, we subtract 4 from both sides of the equation:
2/5x + 4 - 4 = 1/5 - 4
2/5x = 1/5 - 20/5

Simplifying the right side gives:
2/5x = - 19/5

Next, we want to isolate the x variable by multiplying both sides of the equation by its reciprocal, which is 5/2:
(2/5x)(5/2) = (- 19/5)(5/2)
x = -19/10

Therefore, the solution to the equation 2/5x + 4 = 1/5 is x = -19/10.
