To solve the equation \( \frac{1}{2} + x = \frac{3}{5} \), follow these steps:
Subtract \( \frac{1}{2} \) from both sides of the equation:
\[ x = \frac{3}{5} - \frac{1}{2} \]
To perform the subtraction, you need a common denominator. The least common multiple of 5 and 2 is 10. Convert both fractions:
\[ \frac{3}{5} = \frac{3 \times 2}{5 \times 2} = \frac{6}{10} \]
\[ \frac{1}{2} = \frac{1 \times 5}{2 \times 5} = \frac{5}{10} \]
Now, you can subtract:
\[ x = \frac{6}{10} - \frac{5}{10} = \frac{1}{10} \]
So, the solution is:
\[ x = \frac{1}{10} \]
