Beyond the Answer
To solve this system of equations, we can start by manipulating the first equation to express one variable in terms of the other. From the first equation, \( \frac{2x}{3} = 1 + \frac{3y}{2} \). Multiplying through by 6 to eliminate the fractions gives us \( 4x = 6 + 9y \), or \( 4x - 9y = 6 \). Now, we have the equations: 1. \( 4x - 9y = 6 \) 2. \( x + y = 4 \) Next, we can express \( x \) from the second equation as \( x = 4 - y \). Substituting this into the first equation gives us: \( 4(4 - y) - 9y = 6 \) This simplifies to \( 16 - 4y - 9y = 6 \), or \( 16 - 13y = 6 \). Thus, \( -13y = -10 \), leading to \( y = \frac{10}{13} \). Now substituting \( y \) back into \( x + y = 4 \) gives us \( x + \frac{10}{13} = 4 \), so \( x = 4 - \frac{10}{13} = \frac{52}{13} - \frac{10}{13} = \frac{42}{13} \). Thus, the solution is: \( x = \frac{42}{13} \) and \( y = \frac{10}{13} \). Now you have the values of \( x \) and \( y \) in a fraction form that’s not only correct but mathematically sound! 🎉
