Solve: 2n + 3n - 6 = -21

What does n equal?

- n=5
- n=3
- n= -5
- n= -3

n=-3

Step-by-step explanation:

add the like values and add the 6 to the -12 and decide the totals to get -3

n=3

Step-by-step explanation:

2n+3n-6=-21

Add 6 on both sides of the equal sign: -6+6=-21+6

2n+3n=15

Combine like terms: 2n+3n

5n=15

Divide by 5 on both sides of the equal sign: 5n/5=15/5

n=3

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
