The Deep Dive
To solve the system of equations, we can use the substitution or elimination method. Here, let’s use elimination. First, we can align the equations: 1) \( 6x - 5y = 6 \) 2) \( 4x + y = 3 \) Next, we can eliminate \( y \) by manipulating the second equation. Multiply the second equation by 5: \( 20x + 5y = 15 \) Now, add this to the first equation to eliminate \( y \): \( 6x - 5y + 20x + 5y = 6 + 15 \) This simplifies to: \( 26x = 21 \) So, \( x = \frac{21}{26} \). Substitute \( x \) back into the second equation to find \( y \): \( 4\left(\frac{21}{26}\right) + y = 3 \) Solving for \( y \): \( \frac{84}{26} + y = 3 \) \( y = 3 - \frac{84}{26} = \frac{78}{26} - \frac{84}{26} = -\frac{6}{26} = -\frac{3}{13} \). Thus, the solution is \( x = \frac{21}{26} \) and \( y = -\frac{3}{13} \).
