The solution to the given equation is n=-5.
The given equation is 7n+6=4n-9.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, transpose 4n to LHS of the equation and 6 to RHS of the equation, we get
7n-4n=-9-6
3n=-15
n= -15/3
n= -5
Therefore, the solution to the given equation is n=-5.

is my answer correct?
abs(x - 1) > 2
Result one
x - 1 > 2
x > 2 + 1
x > 3 but it does not include 3 so you were right about that.
x - 1 < - 2
x < -2 + 1
x < - 1
Looks like D to me.
Note these questions when they work will give you 2 answers. The second one is always a sign switch.
Again try 2 values. Try 0 and - 2 for x

Answer:
3
Step-by-step explanation:
21 can be divided by 3 also 36
Answer:
3 bouquets
Step-by-step explanation:
Both numbers are divisible by 3, so after division we have 3 groups of 7 carnations, and 3 groups of 12 tulips. 7 is no longer divisible, so if the desire is an even bouquet then we can only make 3 bouquets of 7 carnations and 12 tulips

Answer:
-3n-+21
Step-by-step explanation: 1. Get rid of the Parenthesis , so times -3 by what’s inside
2. If you multiply -3 by n you get -3n
3. if you multiply -3 by -7 you get 21 , you get a positive because a negative times a negative is a positive
4. so now you have -3n + 21 you don’t add these because -3n has a variable and 21 doesn’t have a variable , and if 21 did have a variable it would need to also be n
Answer:
−3n + 21
Step-by-step explanation:
This is the answer because:
1) You have to distribute everything from outside of the parenthesis to the inside
2) -3 times n is -3n
3) -3 times -7 is 21
4) Therefore, the answer is −3n + 21
Hope this helps!
