Question

1. -4x - 10x

Explanation:

Step1: Identify like terms

The terms \(-4x\) and \(-10x\) are like terms (both have the variable \(x\) with the same exponent, 1).

Step2: Combine the coefficients

To combine like terms, we add their coefficients. The coefficient of \(-4x\) is \(-4\) and the coefficient of \(-10x\) is \(-10\). So we calculate \(-4 + (-10)\).
\[
-4 + (-10) = -14
\]

Step3: Attach the variable

After combining the coefficients, we attach the variable \(x\) to the result. So we get \(-14x\).

Answer:

\(-14x\)
