The answer is 35.84.
You just add all of them up
Twice a number can be written as 2n.
Four times the number can be written as 4n.
If the sum of 2n and 4n equals 54, then:
6n = 54
Divide both sides by 6 to solve for n:
n = 9
<h3>
The solution is x = 27</h3>
To undo a log, you raise both sides as exponents. This will cancel out the log on the left side. On the right side you'll have 6^2 turn into 36.
So you should end up with x+9 = 36 after you perform this step. Afterwards, subtract 9 from both sides to end up with x = 27.
G/3 + 11 = 25
Multiply both sides by 3
3.(g/3) + 3 . 11 = 3. 25
g + 33 = 75
subtract 33 from both sides:
g = 75 - 33
g = 42
hope this helps :)
