Question

question 7 find (-7x - 14) - (x - 5).

Explanation:

Step1: Remove parentheses

To remove the parentheses, we distribute the negative sign to the terms inside the second parentheses. So, \((-7x - 14) - (x - 5)\) becomes \(-7x - 14 - x + 5\).

Step2: Combine like terms

Now, we combine the \(x\)-terms and the constant terms separately. For the \(x\)-terms: \(-7x - x = -8x\). For the constant terms: \(-14 + 5 = -9\).

Answer:

\(-8x - 9\)
