Question

Simplify the expressions 4x-2x+1

Answer 1

4x-2x=2x and 1 doesn't have a variable, so the answer in simplified form is 2x+1. I hope this helps you. 

Answer 2

4x - 2x + 1 = 2x + 1

the answer is 2x + 1 because you start with likable terms such as 4x & 2x 
so subtract those and you get 2x then just add the 1 and the simplified expression is: 
2x + 1

Hope this helps and i hope its right 
thank you and have a good day,
