Answer:
y = -1/11 + 5
Step-by-step explanation:
1x + 11y = 55
-1x -1x
11y = -1x + 55
/11 /11
y = -1/11 + 5
Hope this helps!
A = P + I
2a = a + PTR/100
2a = a + 5aT/100
2a = a(1+T/20)
2=1+T/20
T=20 yrs

Why it does not matter?
Let's assume we have 2 numbers, a and b.
When we perform a subtraction:
, we get another number
When we perform another subtraction:
, we get a number
When we raise
