Question

11n-4(2n-3)=18+5(n+2)

Answer 1

distribute the -4 through the parenthesis and distribute the 5 in through the parenthesis.
11n - 4(2n - 3) = 18 + 5(n + 2)
11n - 8n + 12 = 18 + 5n + 10

now combine like terms....get the x's on one side and everything else on the other side. Then, just solve for x. Can you do that ?

Answer 2

3n+12=5n+28

Answer 3

This is where I get stuck. Do I subtract -12 or -28 from both sides?

Answer 4

either one....you can subtract 12 from both sides or you can subtract 28 from both sides. Your main goal is to get the x's on one side, it doesn't matter which side. Either way you do it, whether it is subtracting 12 or subtracting 28, you should get the same answer.

Answer 5

Ohhhh OK Thanks, helps if the teachers tells you that bit of info

Answer 6

try to do the problem and I will check it

Answer 7

ok thanks

Answer 8

11n - 4(2n - 3) = 18 + 5(n + 2)
11n - 8n + 12 = 18 + 5n + 10
3n + 12 = 5n + 28
- 28= -28
3n -16 = 5n
-3n =-3n
-16 =-2n
-2 =-2
8 = n

Kelliegirl33 are you still here? The screen says your replying but its been 10minutes

Answer 10

11n - 8n + 12 = 18 + 5n + 10 (combine like terms)
3n + 12 = 28 + 5n
3n + 12 - 28 = 28 + 5n - 28
3n - 16 = 5n
3n - 3n - 16 = 5n - 3n
-16 = 2n
-16/2 = n
-8 = n

or...
3n + 12 = 28 + 5n
3n + 12 - 12 = 28 + 5n - 12
3n = 16 + 5n
3n - 5n = 16 + 5n - 5n
-2n = 16
n = 16/-2
n = -8

Answer 11

do you see where your mistake was ?

Answer 12

That's what I'm trying to figure out. I got a positive 8

Answer 13

OIC I used a -2

Answer 14

Lets start here....
3n - 16 = 5n....you subtracted 3n...
-3n - 3n
-------------
-16 = 2n (5n - 3n = 2n not -2n)
next, you have to divide by 2 to get n by itself
-16/2 = 2n/2
-16/2 = n
-8 = n

do you understand now ?

Answer 15

as you can see, you can either subtract the 12 or subtract the 28, and you will get the same answer. Just get the x's on one side, either side, and solve for x.

Answer 16

Thank you so much for your help!
