3x - 6y = -2
-6y = -3x - 2, divide through by -1
6y = 3x + 2, divide through by 6
y = 3x/6 + 2/6
y = x/2 + 1/3
Is this the full question that is stated?
Answer:
Since it is a simultaneous equation,
Using elimination method, Multiply equation 1 by the co efficient of x in equation 2 and multiply equation 2 by the co efficient of x in equation 1.

Answer:
n= 13.8 years
Step-by-step explanation:
<u>First, we need to determine the daily interest rate:</u>
Daily interest rate= 0.03 / 365
Daily interest rate= 0.000082
<u>Now, using the following formula we can determine the number of days and years:</u>
n= ln(FV/PV) / ln(1+i)
n= ln(13,000 / 8,600) / ln(1.000082)
n= 5,039 days
<u>In years:</u>
n= 5,039/365
n= 13.8 years
