Question

Subtract -7n + 2 from 2n-1

Answer 1

-9n + 3

Step-by-step explanation:

When you are subtracting something, their signs switch. What that means is the 2n would become -2n and the -1 would become 1. Once you switch the signs, you can add them together.

-7n + 2 - (2n - 1)

-7n + 2 - 2n + 1

Then you add the common numbers

-9n + 3

Answer 2

-9n+3

Step-by-step explanation:

Subtract the second expression ( 2n-1) from the first expression (-7n+3)

2n-7= -9n

+3-1=3

-9n+3
