This is a simultaneous equation
Rearrange the second to give
x - y = 1
Add the two equations
(x + y) + (x - y) = 5 + 1
2x = 6
x=3
Substitute 3 into either equation
3 - 1 = y
y = 2
The sum of n terms of a geometric series is found using the following formula:
where a is the first term and r is the common ratio.
In your question, a = 6 and r = 1/3, so we have:
which simplifies to:
