The answer after subtracting the following equation is x= -8/5

Step-by-step explanation:

  • -2x+7y=10 ----- eq(1) , 3x + 7y =2------ eq(2)

  • 7y+3x =2
  • 7y-2x = 10
  • subtracting eq 2 from eq 1 we get
  • 5x = -8
  • x= -8/5

Please help ASAP!!!!!!!!!!
zepelin [54]

Answer:

(c-a, 0)

Step-by-step explanation:

The horizontal space between (c, b) and P is the same as the space between (a, b) and O.

Coordinates are written (x, y), where x is for horizontal space.

P is on the x-axis, making the y-coordinate 0.

(a+c, 0) would be to the right of the entire parallelogram.

(c, 0) would be directly below (c, b).

(a-c, 0) would be to the left of the entire parallelogram and in the other quadrant.

So if John gives a pen and pencil to each and all of them are over we know that the no. of pencils and pens should be the same
So we will find the LCM of 15 and 40 that is equal to 120
So John brought 120/15 that is 8 packets of pen and 120/40 that is three packets of pencils
