Math Problem Statement
|x| + y = 4
Solution
The equation you've provided is:
To solve this equation, you would typically need to express it in terms of either or . Since it involves an absolute value, the solution can differ depending on the sign of .
Case 1: When
If is positive or zero, . The equation becomes:
This can be rearranged to solve for :
Case 2: When
If is negative, . The equation becomes:
This can be rearranged to solve for :
Final Answer
- For , the equation is .
- For , the equation is .
This represents two linear equations, with the solution depending on whether is non-negative or negative.
