It looks like you've uploaded a problem involving systems of equations in Chinese. From what I can see in the images, the task seems to involve using elimination to solve a system of two linear equations. I'll break down the steps to help you understand how to solve these types of problems.

Here are the equations from the image:

Problem 4:

1. $\frac{1}{4}(x - 2y) = 3$
2. $5x + 4y = -8$

Problem 5:

1. $3x + 3y = -4$
2. $x - y = -1$

Would you like me to walk you through the steps to solve these systems using elimination? Let me know if you'd like more details or a specific explanation for any part of the solution!
