1. \( 7 x-14 y=-56 \)

To solve the equation \( 7x - 14y = -56 \), you can simplify it by dividing all terms by 7, giving you \( x - 2y = -8 \). This is useful because it expresses one variable in terms of the other, making it easier to identify relationships or find specific values when coupled with another equation. Now, if you want to find specific values, you can express \( x \) in terms of \( y \) as \( x = 2y - 8 \). Plug in any value for \( y \) to quickly find the corresponding \( x \) value. For example, if \( y = 0 \), then \( x = -8 \). This method helps you visualize the linear relationship!
