20x-10y=50
10x-15y=-5

y = 3

x = 4

Step-by-step explanation:

20x-10y=50

10x-15y=-5

I will use the elimination method for solving systems of equations.

I want to eliminate x, so I will multiply the bottom equation by negative 2.

20x-10y=50

-2(10x-15y=-5)

thus, I get

20x-10y=50

-20x+30y=10

I can now add these equations and get rid of x.

20y = 60

y = 3

Now, plug in the y value to find x.

20x - (10*3) = 50

20x - 30 = 50

20x = 80

x = 4

Check your answer by plugging in the x and y values to see if the equation is correct!

(20*4) - (10*3) = 50

80 - 30 = 50

The solution works for the first equation

(10 *4) - (15 * 3) = -5

40 - 45 = -5

The solution also works for the second equation.

This solution is correct

step-by-step explanation:

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
