Answer :

To simplify the expression [tex]\(4s + 5t - 2s\)[/tex], follow these steps:

1. Identify Like Terms:
- Like terms are terms that have the same variable raised to the same power. In this expression, [tex]\(4s\)[/tex] and [tex]\(-2s\)[/tex] are like terms because they both contain the variable [tex]\(s\)[/tex].

2. Combine Like Terms:
- Add or subtract the coefficients of the like terms. Here, you subtract [tex]\(2s\)[/tex] from [tex]\(4s\)[/tex]:
[tex]\[
4s - 2s = 2s
\][/tex]

3. Rewrite the Expression:
- After combining the like terms, rewrite the expression with the remaining term:
[tex]\[
2s + 5t
\][/tex]

So, the simplified expression is [tex]\(2s + 5t\)[/tex].
