1) 2x+8y=20

y=2

2x+8 (2) = 20

2) x=5

2x+y=10

2 (5) + y=10

3) 5x-2y=3

y=2x

5x-2 (2x) = 3

4) 2y+x=-15

x=3y

2y + (3x) = - 15

5) 4x+7y=19

y=x+9

4x+7 (x+9) = 19

6) y=6x+11

2y-4x+14

2 (6x+11) - 4x+14

7) 2x-8y=6

y=-7-x

2x-8 (-7-x) = 6

8) x=2y-1

3x-2y=-3

3 (2y-1) - 2y=-3

what is the process and what x and y equal

    If they give you what one variable is, you can plug it into the equation and use algebra to solve it. So:

    1) 2x=4 - > 4/2 = 2 so x=2

    2) y=0

    3) x=3

    4) 2y + (3*3y) = - 15

    11y=-15

    y = - 15/11

    5) 4x + 7x + 63 = 19

    11x = - 44

    x = - 4
