Answer:
a = =36
Step-by-step explanation:
a + 6 = -30
make a on its own
a = -30 - 6
a = =36
Represent Age of Time Traveler =========> X
Solve:
x = 3(x - 20 )
Step 1: Simplify Both sides of equation:
x = 3(x - 20 )
x = (3) (x) + (3) ( - 20 ) (Distribute ):
x = 3x + - 60
x = 3x - 60
Step 2: Subtract 3x from both sides:
x - 3x = 3x - 60 - 3x
- 2x = - 60
Step 3: Divide both sides by -2:
- 2x / - 2 = - 60 / - 2
x = 30
Answer: Our Time Traveler is 30 years old.

The solution for s in the given equation is 
The question seems to be incomplete
Here is the complete question:
Solve for s in this equation 
Depreciation.
To solve for s, that means we should make s the subject of the equation
From the given equation,
To solve for s, first multiply both sides by n to clear the fraction
We get
Then,
Now, add s to both sides
Then, subtract nD from both sides
∴
Hence, the solution for s in the given equation is
