Answer:
2x
Explanation:
For this problem, we can tackle it by using the distributive property and factoring. We are given the following expression:
3x + 4x - 5x
And are told to simplify the expression. Let's factor out the x from all the terms, and then simply use addition to simplify. From here we can redistribute the x to gain our simplified expression:
3x + 4x - 5x
= x ( 3 + 4 - 5 )
= x ( 7 - 5 )
= x ( 2 )
= 2x
Hence, the simplification of the expression 3x + 4x - 5x is 2x.
Cheers.
