You can "plug in" the value for y from the top eq in the bottom one:

3(-2x+6) - x + 3 = 0

Simplify:

-6x + 18 - x + 3 = 0

-7x + 21 = 0

-7x = -21

x = 3

y = -2*3+6 = 0

1. Refer to the equation 2x − 6y = 12. (a) Create a table of values for at least 4 points. Show your work.
Sergio039 [100]
2x - 6y = 12

so we pick any number for x and then solve for y

lets say x = 0
2(0) - 6y = 12
-6y = 12
y = -12/6
y = -2....so when x = 0, y = -2....(0,-2) <== one point

lets say x = 1
2(1) - 6x = 12
2 - 6x = 12
-6x = 12 - 2
-6x = 10
x = -10/6
x = - 5/3...so when x = 1, y = -5/3....(1,-5/3) <== another point

Lets say x = 2
2(2) - 6y = 12
4 - 6y = 12
-6y = 12 - 4
-6y = 8
y = -8/6
y = - 4/3....so when x = 2, y = -4/3.....(2,-4/3) <== another point

lets say x = 3
2(3) - 6y = 12
6 - 6y = 12
-6y = 12 - 6
-6y = 6
y = -6/6
y = -1....so when x = 3, y = -1.....(3,-1) <== another point

now there is 4 points.
