how do you solve this? 3(2n-3)+4(n-2)=13?

3(2n - 3) + 4(n - 2) = 13
3*2n - 3*3 + 4*n - 4*2 = 13
6n - 9 + 4n - 8 = 13
6n + 4n = 13 + 9 + 8
10n = 30
n = 30/10
n = 3

distribute:
6n-9 + 4n-8 =13

combine like terms:
10n-17=13

add 17 to each side:
10n=30

divide by 10:
n=3

substitute 2 back in for n:
3(2(3)-3) + 4((3)-2) =13
9+4=13
13=13

6n + 4n - 9 - 8 = 13
10 n = 30
n = 3

shame on u man ...u dnt know how to solve this!!!!!!!

look here.....its..
3(2n-3)+4(n-2)=13
(by multiplying 3 with 2n and then with -3) (then multiplying 4 with n and then -2).......

=>> 6n-9+4n-8=13
(then adding and sub. the like and unlike terms)

==>> 10n-17=13

==>> 10n = 13+17

==>> 10n = 30

==>> n =30/10

===>> n = 3(answer)


now..you've got the value of "n"...put it in the equation...........

the equation is....3(2n-3)+4(n-2)

(putting value of n in the equation)....

3(2*3-3)+4(3-2)

==> 3(6-3)+4(1)

==>> 3*3+4*1

==>> 9+4

==>>13


therefore w've got the answer = 13

it was simple brother.......

holla..

6n - 9 + 4n - 8 = 13
10n =13 + 9 + 8
10n = 30
10n / 10 = 30 / 10
n = 3

3(2n-3)+4(n-2)=13
distribute
6n-9+4n-8=13
add similar terms
10n-17=13
10n=13+17
10n=30
divide both sides by 10
10n/10=30/10
n=3

to check if the answer is correct..just substitute ur answer to n.


3(2n-3) + 4(n-2)=13
3(3 *2)-3)+4(3-2)=13
3(6-3)+4(1)=13
3(3)+4=13
9+4=13
13=13

meaning the answer is correct..:D

6n-9+4n-8=13
10n=30
n=3

N=3 just put that number into the equation and check it works
