Final answer:
To solve exercises 53-55 algebraically, we need to find the specific equations of the lines provided in the exercise and follow further steps to solve them.
Step-by-step explanation:
To solve exercises 53-55 algebraically, we need to find the specific equations of the lines provided in the exercise. Let's take the example of exercise 53. Suppose we have two lines represented by the equations y = mx + b1 and y = mx + b2, where m is the slope and b1 and b2 are the y-intercepts of the lines.
To find the equations of the lines, we need to know the values of m, b1, and b2, which can be provided in the exercise or given. Once we have the equations of the lines, we can follow further steps to solve the exercise as required.
