Step-by-step solution

To solve this problem, we'll employ the method of cross-multiplication:

  1. First, we start with the equation x5=x+310 \frac{x}{5} = \frac{x+3}{10} .
  2. Apply cross-multiplication: 10x=5(x+3) 10x = 5(x + 3) .
  3. Distribute on the right-hand side: 10x=5x+15 10x = 5x + 15 .
  4. Subtract 5x 5x from both sides to isolate terms involving x x :
    10x5x=15 10x - 5x = 15 .
  5. This simplifies to 5x=15 5x = 15 .
  6. Divide both sides by 5 to solve for x x :
    x=155 x = \frac{15}{5} .
  7. Simplifying the fraction, we find x=3 x = 3 .

Therefore, upon reviewing the correct process and calculations, the solution to the problem is x=3 x = 3 .
