1. Problem Description

The problem is to solve the linear equation 2x5=3x+1\frac{2x}{5} = 3x + 1 for xx.

2. Solution Steps

First, we multiply both sides of the equation by 5 to eliminate the fraction:
52x5=5(3x+1)5 \cdot \frac{2x}{5} = 5 \cdot (3x + 1)
2x=15x+52x = 15x + 5
Next, subtract 15x15x from both sides of the equation:
2x15x=15x+515x2x - 15x = 15x + 5 - 15x
13x=5-13x = 5
Finally, divide both sides of the equation by -13 to isolate xx:
13x13=513\frac{-13x}{-13} = \frac{5}{-13}
x=513x = -\frac{5}{13}

3. Final Answer

x=513x = -\frac{5}{13}
