Use the elimination method by subtraction to solve for x and then y.

Mathematics
1 answer:
diamong [38]3 years ago
7 0

Answer:

Step-by-step explanation:

Both equations have -7y. You can eliminate them by subtracting one equation from the other:

Multiply equation 1 by -1, then add it to equation 2:

-2x + 7y = 74

3x - 7y = -83

———————

x = -9

2x - 7y = -74

2(-9) - 7y = -74

-7y = -56

Y = 8

(x,y) = (-9, 8)

I need help please will give brainliest
EleoNora [17]

Answer:

1.) True, because it says three times so you know the x belongs there. Also, you have to follow the order of what the problem says.

2.) False, because it is not in the order of how the problem states it.

3.) False, because if you transfer the fraction to a decimal you get 4.333333. It's not valid.

4.) True, because if you do 7 × 3, it equals to 21. So, 21 - 17 = 4. And Jenny is supposed to have 4 quilts.

Hope it helps! :D
