Answer:
no solutions
Step-by-step explanation:
6n - 6n - 12 = 14 - 2 = 12 ( add 12 to both sides )
0 = 24 ← not possible
this indicates the equation has no solution

Hope this helps.
Answer:
x=12
Step-by-step explanation:
This is an equilateral triangle. That means all the angles are equal
There are three angles and they add to 180. 180/3 =60. Each angle is equal to 60
4x+12 =60
Subtract 12 from each side
4x+12-12 = 60-12
4x = 48
Divide by 4
4x/4 =48/4
x=12
Since the operation between the two sets of parentheses is addition, we don't have to do anything with it, and can remove the parentheses.
Our new expression is: 2y^2+9y+4-3y^2-3y-9
Now, we just add like terms together to solve for the simplest form of the expression.
2y^2+9y+4-3y^2-3y-9
(2-3)y^2+(9-3)y+(4-9)
-y^2+6y-5
Our final answer is -y^2+6y-5.
