4x row 3 box 2 that’s the only one I know
satela [25.4K]3 years ago
6 0

Step-by-step explanation:

Start filling in from the bottom, left to right

<u>Row 2 from bottom:</u>

  • -2x + 3
  • 3 + (-5) = -2
  • -5 + 7y = 7y - 5
  • 7y + 1

<u>Row 3 from bottom:</u>

  • 2x + (-2x) + 3 = 3
  • -2x + 3 + (-2) = -2x + 1
  • -2 + 7y - 5 = 7y - 7

<u>Row 4 from bottom:</u>

  • 3 + (-2x) + 1 = -2x + 4
  • 7y - 7 - 5 + 15y =  22y - 12

<u>Row 5 from bottom:</u>

  • -2x + 4 -2x - 6 + 7y = -4x + 7y - 2
  • -2x - 6 + 7y + 22y - 12 = -2x + 29y - 18

<u>Top row:</u>

  • -4x + 7y - 2 - 2x + 29y - 18 = -6x + 36y - 20

Y=2/7 -7 y=-x+2 What is the solution for this system of equations?​
bulgar [2K]

Answer:

(61/7, -47/7)

Step-by-step explanation:

Given: y=2/7 -7

           y=-x+2

Rewrite the top equation ( y=2/7 -7

y = -47/7

y = -x + 2

Because both equations are equal to y, we can rewrite it again.

-47/7 = -x + 2

Add x to both sides

x + (-47/7) = 2

Add 47/7 to both sides.

x = 47/7 + 2/1

x = 61/7

As stated in the beginning, y is equal to -47/7

Hope you understand!
