To solve the system of equations, let's rewrite the second equation to eliminate the fraction: 1. The first equation is \( 4y + x = 4 \). 2. The second equation can be rewritten as \( y - 2x = 2(x - 1) \) which simplifies to \( y - 2x = 2x - 2 \), leading to \( y = 4x - 2 \). Now we can substitute \( y = 4x - 2 \) into the first equation: \( 4(4x - 2) + x = 4 \) Expanding this gives: \( 16x - 8 + x = 4 \) Combining like terms results in: \( 17x - 8 = 4 \) Adding 8 to both sides: \( 17x = 12 \) Dividing by 17: \( x = \frac{12}{17} \) Now substituting \( x \) back into \( y = 4x - 2 \): \( y = 4\left(\frac{12}{17}\right) - 2 = \frac{48}{17} - \frac{34}{17} = \frac{14}{17} \) The solution to the system is \( x = \frac{12}{17} \) and \( y = \frac{14}{17} \).
