Answer:

A. x= 3, y= -2

Step-by-step explanation:

[2] 2x= 4y+14

[1] 3y+5x=9

Solve equation [2] for the variable  x

 [2]    2x = 4y + 14

 [2]    x = 2y + 7

// Plug this in for variable  x  in equation [1]

  [1]    5•(2y+7) + 3y = 9

  [1]    13y = -26

// Solve equation [1] for the variable  y

  [1]    13y = - 26

  [1]    y = - 2

// By now we know this much :

   x = 2y+7

   y = -2

// Use the  y  value to solve for  x

   x = 2(-2)+7 = 3

good luck, I hope this helps!!!

How do i solve the system of equations by graphing?<br>2x+y=7 <br>x-2y=6
scoray [572]

Answer:


Step-by-step explanation:

1. y = -2x + 7

2. Graph it (Mark (0, 7) or 7 on the y axis and go over one, down two, mark it and draw a line through both)

3. -2y = -x + 6

4. divide entire equation by 2 to isolate y

5. -y = -x + 3

6. multiply entire equation by -1 to make it positive

7. y=x+3

8. graph it (Mark (0,3) and go over one, down one, mark it and draw a line through both new points)

9. Where the lines intersect is your answer
