To solve the equation, you can follow these steps:
Step 1: Start by subtracting 4 from both sides of the equation to isolate the fraction term:
2/5x + 4 - 4 = 1/5 - 4
2/5x = 1/5 - 4
Step 2: Simplify the right side of the equation:
2/5x = 1/5 - 20/5
2/5x = -19/5
Step 3: To get rid of the fraction, multiply both sides of the equation by the reciprocal of the fraction's coefficient (5/2):
(5/2)(2/5x) = (5/2)(-19/5)
x = -19/2
So, the solution to the equation is x = -19/2.
