To solve the system of equations \( 8 x-10 y=-23 \) and \( 9 x+10 y=-16 \), you can use the elimination or substitution method. When you bring the equations into a form that makes it easy to eliminate one variable, you'll find the values of \( x \) and \( y \). After calculations, the approximate solution is \( (-2.5, 1) \). When working with systems of linear equations, it's key to double-check your arithmetic and ensure you're not making small mistakes with signs or calculations. Common pitfalls include misreading coefficients or incorrectly applying elimination methods, so keeping your work organized is a must!
