Each group of 2 nickels and 1 quarter has a value of $0.35. Rachelle has $6.30/$0.35 = 18 such groups.

Rachelle has 18 quarters and 36 nickels.

The first step is to define the system of equations.

Take x and y as the cost of a small box and a large box respectively.

$\begin{gathered} 2x+y=12 \\ 3x+y=16 \end{gathered}$

Solve the system.

$\begin{gathered} 2x+y=12 \\ y=12-2x \\ 3x+y=16 \\ y=16-3x \end{gathered}$ $\begin{gathered} 12-2x=16-3x \\ 3x-2x=16-12 \\ x=4 \end{gathered}$ $\begin{gathered} y=12-2x \\ y=12-2\cdot4 \\ y=12-8 \\ y=4 \end{gathered}$

A small box costs $4 and a large box costs $4 too.

Answer:

y= -7

Step-by-step explanation:

So first distribute the 8

4=8y+32-4y

now combine like terms (the -4y+8y)

4=32+4y

Subtract 32 on both sides to isolate 4y

-28=4y

now divide 4 on both sides to isolate Y

-7=y

so y= -7

Savatey [412]

The answer would be (-1, -1) on a coordinate grid.

(-6+4)/2=x
(-2)/2=x
-1=x

(5+-7)/2=y
(-2)/2=y
-1=y
