Answer:
7x + 1 and 5x + 2x + 1
Explanation:
Hi!
To write two equivalent expressions, we can just simplify it.
3x+4x+1=
3x+4x can be added together, since they both have the same variable, so:
3x+4x+1 = 7x + 1
Using 7x+1, we could write a lot of different combinations since:
3+4=7
5+2=7
6+1=7
Using this, the second equivalent expression could be:
5x+2x+1
or
6x+1x+1
And that’s it! I hope this helped, let me know if you have any questions.
