EXPLANATION.

To perform the subtraction of the two binomials we must follow the following steps:

-Order the binomials (we must add or subtract values ​​with the same variable)

-Change the sign of the second binomial or subtrahend.

The exercise is as follows:


\begin{gathered} (3w-4x)-(2x-w); \\ (3w-4x)+(-2x+w);\text{ here }we\text{ change sign} \\ (3w+w)+(-4x-2x);\text{ }here\text{ we group }the\text{ same variable} \\ 4w+(-6x) \\ 4w-6x \\ \text{ANSWER: 4w-6x} \end{gathered}
