Sum of a finite geometric series=a(r^(n) -1)/(r -1)
or
sum of a finite geometric series=a(1 - r^(n))/(1 - r)

Answer:
So first, they remove the denominator of x times x, because multiplication cancels out division, so then you're left with
3/1 times x = 2193
3/1 just equals three, so you write it down as 3.
3x = 2193
To isolate 3x, you need to divide by 3.
x = 731
Hope this helped :)
Answer:
The answer is x = 5
Step-by-step explanation:
The given equation is
25 - 3x = 10
So when we break down this equation, we will have the value of x. Now breaking down the equation and moving variables to the correct positions.
25 - 3x = 10
Moving -3x and 10 to the other sides
25 - 10 = 3x
3x = 25 - 10
3x = 15
Now dividing both sides with 3, we get the following answer
3x/3 = 15/3
x = 5
Breaking down the equation gives us the value of x, i-e 5
