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 \(23\).

1 answer

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

Remove parentheses: Since both terms are being added, you can drop the parentheses. \[ 7x + 8 + 15 - 7x \]
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 \(23\).
