15×+14×=2215

To solve the equation \( 15x + 14x = 2215 \), you can combine the like terms on the left side. 1. Combine the terms: \[ (15x + 14x) = 29x \] Thus, the equation becomes: \[ 29x = 2215 \] 2. Now, solve for \( x \) by dividing both sides by 29: \[ x = \frac{2215}{29} \] 3. Perform the division: \[ x = 76.03 \] Therefore, the solution to the equation \( 15x + 14x = 2215 \) is: \[ x \approx 76.03 \] or \(*if you simplify \( \frac{2215}{29} \)*\). If you need the exact value, you might choose to clarify the expectation of the degree of precision required in exams.
