9n +12=6n +54 what is n and how do you get it
9n +12=6n +54
9n - 6n = 54 - 12
3n = 42
n = 42/3
n = 14
9n + 12= 6n =54
-6n -6n
3n + 12=54
-12 -12
3n=42
n= 14
what you did was take 6n and subtract it from both sides (from 9n & 6n) you get 3n and 7 & -6 cancel because of opposite signs and u are left with 3n+ 12=54 , then you subtract 12 from both sides again & 12 & -12 cancel because of opposite signs & 54-12 is 42 & you are left with 3n=42 and then divided 3 by 42 and 3n and n equals 12 .
To find the value of n in the equation 9n + 12 = 6n + 54, we can solve for n by following these steps:
Step 1: Combine like terms
First, we want to combine the terms with n on one side of the equation and the constant terms on the other side. To do this, subtract 6n from both sides of the equation:
9n + 12 - 6n = 6n + 54 - 6n
Simplifying this, we get:
3n + 12 = 54
Step 2: Isolate the variable term
Next, we want to isolate the variable term on one side of the equation. In this case, we want to move the constant term (12) to the other side by subtracting it from both sides of the equation:
3n + 12 - 12 = 54 - 12
Simplifying this, we get:
3n = 42
Step 3: Solve for n
Finally, we can solve for n by dividing both sides of the equation by the coefficient of n (which is 3):
(3n) / 3 = (42) / 3
Simplifying this, we get:
n = 14
Therefore, the value of n in the equation 9n + 12 = 6n + 54 is 14.
