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

Question

A. - 38/25
B. 21/2
C. - 19/2
D. - 2/19

Answer 1

C. - 19/2

To solve for x, first subtract 4 from both sides of the equation:

2/5x + 4 - 4 = 1/5 - 4
2/5x = -19/5

Now multiply both sides 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 is x = -19/2.
