The solution to the equation can be found by isolating the variable x.
2/5x + 4 = 1/5
First, we can subtract 4 from both sides of the equation:
2/5x = 1/5 - 4
Simplifying the right side:
2/5x = 1/5 - 20/5
Combining the fractions:
2/5x = -19/5
To isolate x, we can multiply both sides of the equation by the reciprocal of 2/5:
x = (-19/5) * (5/2)
The common factors cancel out:
x = -19/2
Therefore, the solution to the equation is: x = -19/2
The correct answer is: b. −19/2
