What is the result of subtracting the second equation from the first? -2x+y=0 - 7x + 3y = 2

Answer:

5x - 2y = - 2

Step-by-step explanation:

Given the 2 equations

- 2x + y = 0 → (1)

- 7x + 3y = 2 → (2)

Subtracting (2) from (1) term by term

- 2x - (- 7x) + y - 3y = 0 - 2, that is

- 2x + 7x - 2y = - 2

5x - 2y = - 2

Answer:

11 bushels of apples were sold

Step-by-step explanation:

Let

x---->  bushels of peaches

y---->  bushels of apples

we know that

7x+6y=346 -----> equation A

x=y+29 -----> equation B

substitute equation B in equation A and solve for y

7(y+29)+6y=346

7y+203+6y=346

13y=346-203

13y=143

y=143/13=11

100 equals 15 minus x divided by 5
zloy xaker [14]
The answer is -485. 

To find this we first need to get rid of the 5 in the denominator. 

100 = \frac{15 - x}{5}

So we multiply each side by 5. 

 500 = 15 - x

Now we need to get rid of the 15. So we subtract 15 from both sides. 

485 = -x

Then since our x is negative, we need to divide by -1. 

-485 = x
