Solve each system by multiplying. Check ur answer.
kondor19780726 [428]
Multiply all terms in the first equation by 2 and all terms in the second by 3.
You should obtain:

6x + 16y = 34
-6x + 27y = 9
------------------
       43y =43, and so y = 1.  Subbing 1 for y in the first eq'n, we get

3x + 8(1) = 17, or 3x = 9, or x = 3.

The solution is (3, 1).

professor190 [17]
Well, from 2008 to 2010 is just 2 years, so let's say the initial amount is the 19300 from 2008, how many will it be in 2010?

\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &19300\\
r=rate\to 20\%\to \frac{20}{100}\to &0.20\\
t=\textit{elapsed time}\to &2\\
\end{cases}
\\\\\\
A=19300(1+0.2)^2
