Equation 2 is 6 times the equation 1.

<u>Explanation:</u>

Given:

-5x - 8y = 4                       -1

-30x - 48y = 24                -2

The 2nd equation can be simplified in following steps:

-30x - 48y = 24

Dividing both left and right hand side by 2. We get

-15x - 24y = 12

Dividing the equation further by 3 on both the sides. We get

-5x - 8y = 4                       -3

We can see that on simplification of equation 2, it becomes same as equation 1.

Therefore, equation 2 is 6 times the equation 1.

Two families are shopping for a camping trip. The first family buys 3 flashlights and 4 sleeping bags at a cost of $118. The sec
Sliva [168]

Answer:

3x +4y = 118

5x+6y =180

y= $25

Step-by-step explanation:

Let x = the cost of a flashlight

Let y = the cost of a sleeping bag

3x +4y = 118

5x+6y =180

Multiply the first equation by -5

-5(3x +4y) = -5*118

-15x -20y = -590


Multiply the second equation by 3

3(5x+6y) =3*180

15x + 18y = 540

Add the modified equations together.

We are using elimination to eliminate the variable x

-15x -20y = -590

15x + 18y = 540

----------------------------

-2y = -50

Divide by -2

-2y/-2 = -50/-2

y =25

Each sleeping bag costs $25
