Simplifying Algebraic Expressions: (2x-3)-(4x-5)-(-x+3)
This article will guide you through simplifying the algebraic expression: (2x-3)-(4x-5)-(-x+3)
Understanding the Problem
The expression involves several terms with variables and constants. We need to combine like terms to simplify it.
Steps to Simplify
-
Distribute the negative signs: Remember that subtracting a term is the same as adding its negative. So, we have:
(2x - 3) + (-1)(4x - 5) + (-1)(-x + 3)
-
Multiply the negative signs:
2x - 3 - 4x + 5 + x - 3
-
Combine like terms: Group the 'x' terms together and the constant terms together.
(2x - 4x + x) + (-3 + 5 - 3)
-
Simplify the expression:
-x - 1
Final Result
Therefore, the simplified form of the expression (2x-3)-(4x-5)-(-x+3) is -x - 1.
Key Takeaways
