1/3+х=7/15

To solve the equation \( \frac{1}{3} + x = \frac{7}{15} \), follow these steps:

1. First, we need to isolate \( x \). Start by subtracting \( \frac{1}{3} \) from both sides:

\[ x = \frac{7}{15} - \frac{1}{3} \]

2. To subtract the fractions, we need a common denominator. The denominator for \( \frac{1}{3} \) can be converted to a denominator of 15:

\[ \frac{1}{3} = \frac{5}{15} \]

3. Now substitute this back into the equation:

\[ x = \frac{7}{15} - \frac{5}{15} \]

4. Now perform the subtraction:

\[ x = \frac{7 - 5}{15} = \frac{2}{15} \]

Thus, the solution is:

\[ x = \frac{2}{15} \]
