If you would like to solve the system of equations, you can do this using the following steps:

-3x + 4y = 12
x * 1/4 - 1/3 * y = 1 ... x * 1/4 = 1 + 1/3 * y ... x = 4 + 4/3 * y
_____________
<span>-3x + 4y = 12
</span>-3 * (4 + 4/3 * y) + 4y = 12
-12 - 4y + 4y = 12
-12 = 12
-12 - 12 = 0
-24 = 0

The correct result would be: <span>the system of the equations has no solution; the two lines are parallel.</span>

babymother [125]

Answer:

Shipping Cost of small boxes = x = $7

Shipping Cost of large boxes = y = $15

Step-by-step explanation:

Let us represent

Shipping Cost of small boxes = x

Shipping Cost of large boxes = y

The postal service offers flat-rate shipping for priority mail in special boxes.

Today, Kylie shipped 4 small boxes and 4 medium boxes, which cost her $88 to ship.

4x + 4y = 88...... Equation 1

Meanwhile, Trevor shipped 9 small boxes and 4 medium boxes, and paid $123.

9x + 4y = 123 ..... Equation 2

Combining both Equations

4x + 4y = 88...... Equation 1

9x + 4y = 123 ..... Equation 2

Subtract Equation 1 from Equation 2

5x = 35

x = 35/5

x = $7

Solving for y using Equation 1

4x + 4y = 88...... Equation 1

4($7) + 4y = 88

28 + 4y = 88

4y = 88 - 28

4y = 60

y = 60/4

y = $15

Shipping Cost of small boxes = x = $7

Shipping Cost of large boxes = y = $15
