      3x - 4y = 7
    -(3x + 2y = -5)

=     0 - 6y = 12
          -6y = 12
             y = -2
The resulting equation would be y = -2.

nalin [4]

Answer: shameeka sold 20 hamsters to the store.

Step-by-step explanation:

Let x represent the number of hamsters that shameeka sold to the store.

Let y represent the number of hamsters that the pet store had initially.

Shameeka sold her hamsters to a pet store. This doubled the number of hamsters in the store. It means that

x + y = 2y

x = 2y - y

x = y

Then the store got six more hamsters. If the pet store has 46 hamsters now, it means that

2y + 6 = 46

2y = 46 - 6

2y = 40

y = 40/2

y = 20

Since x = y, then

x = 20

A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$37644\\
r=rate\to 12\%\to \frac{12}{100}\to &0.12\\
n=
\begin{array}{llll}
\textit{times it compounds per year}\\
\textit{semiannually, thus twice}

\\\\\\
A=37644\left(1+\frac{0.12}{2}\right)^{2\cdot 4}\implies A=37644(1.06)^8
