Question

(7x + 8) + (15 - 7x)

Answer 1

To simplify the expression \((7x + 8) + (15 - 7x)\), you can follow these steps:

1. **Remove parentheses**: Since both terms are being added, you can drop the parentheses.
\[
7x + 8 + 15 - 7x
\]

2. **Combine like terms**:
- Combine the \(7x\) and \(-7x\):
\[
7x - 7x = 0
\]
- Combine the constant terms \(8\) and \(15\):
\[
8 + 15 = 23
\]

Putting it all together, you have:

\[
0 + 23 = 23
\]

So, the simplified form of \((7x + 8) + (15 - 7x)\) is \(23\).
