I need to know how to work this math problem: 3n + (-7) -5n +1
3n + (-7) -5n +1
3n - 5n + 6
-2n + 6
Like Ms. Sue showed, you need to combine like terms.
3n-5n=-2n
-7+1=-6
You cannot combine -2n and -6 so the answer would be -2n-6.
-2n-6
To simplify the expression 3n + (-7) - 5n + 1, you can follow these steps:
1. Combine the like terms (terms with the same variable raised to the same power). In this case, the terms are 3n and -5n. Adding them together, we get -2n.
So far, the expression becomes: -2n + (-7) + 1
2. Simplify the constants. In this case, -7 and 1 can be added to get -6.
Now, the expression simplifies to: -2n - 6
Therefore, the simplified form of 3n + (-7) - 5n + 1 is -2n - 6.
