Answer:

$2x + 2(x - 3) = 18 \\ 2x + 2x - 6 = 18 \\ 4x = 24 \\ x = 24 \div 4 = 6 \\ y = x - 3 = 6 - 3 = 3$

Answer:

31000 dollars were invested at 4% interest rate.

16000 dollars were invested at 5% interest rate.

Step-by-step explanation:

Convert the interest rate into decimal and then write down two equations to solve for the unknowns.

$\begin{bmatrix}0.04x+0.06y=2200\\ x+y=47000\end{bmatrix}$

$\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}\\\\x=31000,\:y=16000$
