my answers are in green, and I have no idea how to complete the last part. What is happening?
what does C = c + 4 mean?
Does it work? IOW, does it satisfy u - 2v = 3?goonking said:Ok, so it means the difference between the two numbers is 4?
so then it should be (3 , -2) + C(1, 1/2) ?
Sure, that works.goonking said:(3,0) + C(1, 1/2)
I asked you whether your answer satisfied u - 2v = 3. Do you understand why it does or does not?goonking said:so then it should be (3 , -2) + C(1, 1/2) ?
yes, this is much easier than the Yn and Yp stuff. I just need to connect the pieces to the puzzle.Mark44 said:Earlier you said this:

This problem is a simplified version of the business with a complementary solution and a particular solution. It helps to think in terms of vectors.goonking said:yes, this is much easier than the Yn and Yp stuff. I just need to connect the pieces to the puzzle.
The equation C = c + 4 is a mathematical expression that represents the relationship between two variables. The variable C stands for a larger quantity, while c represents a smaller quantity. The equation states that the larger quantity, C, is equal to the smaller quantity, c, plus 4.
To solve for C in this equation, you can simply subtract 4 from both sides. This will result in C = c. This means that the value of C is equal to the value of c.
Yes, you can rearrange the equation to solve for c. To do this, you can subtract c from both sides, which will result in C - c = 4. This means that the value of c is equal to the value of C minus 4.
To substitute values into this equation, you can simply replace the variables C and c with the given values. For example, if C = 10 and c = 6, the equation would become 10 = 6 + 4. This can then be solved to find the value of either C or c.
Yes, you can use this equation to solve real-world problems that involve two quantities that are related by a difference of 4. For example, if you are given the total number of students in a class (C) and the number of girls (c), you can use this equation to find the number of boys in the class by subtracting 4 from the total number of students.
