Answer:
The expression \((a + x) - (b + y)\) can be simplified using basic algebraic rules:
\[
(a + x) - (b + y) = a + x - b - y
\]
Now, combine like terms (terms with \(a\), \(x\), \(b\), and \(y\)):
\[
a - b + x - y
\]
Therefore, the value of \((a + x) - (b + y)\) simplifies to \(a - b + x - y\).
Answer:
Explanation:To find the value of \( (a + x) - (b + y) \), we distribute the subtraction across the parentheses:
\[ (a + x) - (b + y) = a + x - b - y \]
Now, combine like terms:
\[ a + x - b - y \]
So, the value of \( (a + x) - (b + y) \) is \( a + x - b - y \).
