Math Problem Statement

Find x and if(x - y, x + y) = (6, 10)

Solution

The equation given is (xy,x+y)=(6,10)(x - y, x + y) = (6, 10).

This can be interpreted as two separate equations:

  1. xy=6x - y = 6
  2. x+y=10x + y = 10

Now, let's solve for xx and yy:

Step 1: Add the two equations

(xy)+(x+y)=6+10(x - y) + (x + y) = 6 + 10 2x=162x = 16 x=162=8x = \frac{16}{2} = 8

Step 2: Substitute x=8x = 8 into one of the original equations

Using the first equation xy=6x - y = 6: 8y=68 - y = 6 y=86=2y = 8 - 6 = 2

Thus, x=8x = 8 and y=2y = 2.

Would you like a detailed explanation or have any questions about this? Here are five related questions to explore further:

  1. How would the result change if (x+y)=12(x + y) = 12 instead of 10?
  2. Can you solve the system of equations using substitution instead of addition?
  3. What is the geometric interpretation of solving xyx - y and x+yx + y simultaneously?
  4. How would you solve for xx and yy if fractional values were involved?
  5. How does solving linear systems like this apply to real-world problems?

Tip: Always check your solution by substituting values back into the original equations!
