2n+3n+7=-41
5n+7= -41
5n= -41-7
5n= -48
n = -48/5
or, n = - 9.6

2n+3n=5n
5n+7= -41 then you subtract 7 from both sides to be left with
5n= -48
Divide 5 from each side to have the N by itself.
n= -48/5

2n + 3n + 7 = -40-one 2n and 3n are like variables. upload 5n + 7 = -40-one Subtract 7 from -40-one 5n = -40 8 Divide -40 8 by making use of 5 n = -9.6 You get -9.6. because of the fact a detrimental divided by making use of a great is detrimental.

Combine like terms.
5n = - 41 - 7 = - 48
Divide both sides of the equation by 5.
n = - 48 / 5 = - 9 3/5.

1st we combine like terms:
2n+3n+7=-41
5n+7=-41
5n=-41-7
5n=-48
then divide 5 by -48
the answer is -81.6
