✔ 最佳答案
If y = -x, then you are adding a number to it's own negative, which will always be 0. The question is invalid.

resolve right here structures of equations for x and y a million). y = 3 + 3x y = 18 - 2x 3x - y = -3 2x + y = 18 5x = 15 x = 3 y = 12 2). 18x + 6y = one hundred twenty 4x + 3y = 40 8x + 6y = 80 10x = 40 x = 4 y = 8

6x + 6y = -2
6x = -6y - 2
x = (-6y - 2)/6
x = -6y/6 - 2/6
x = -y - 2/6
Substitute -x for y.
x = -(-x) - 2/6
x = x - 2/6
x - x = -2/6
0 = -2/6
(no solution)
6x = -6y - 2
x = (-6y - 2)/6
x = -6y/6 - 2/6
x = -y - 2/6
Substitute -x for y.
x = -(-x) - 2/6
x = x - 2/6
x - x = -2/6
0 = -2/6
(no solution)

6x + 6y = -2
y = -x
6x+6(-x)=-2
6x-6x=-2
0=-2
therefore there is no solution in this following equation..
y = -x
6x+6(-x)=-2
6x-6x=-2
0=-2
therefore there is no solution in this following equation..

Solution:
(1) 6x + 6y = -2 AND (2) y = -x
Sub (2) into (1) as below:
6x + 6(-x) = -2
6x - 6x = -2
0 = -2
Hence no Solution.

Hence no Solution.

this system has no solution set.
if y= -x, then -y=x
if u plug in -y for x,
u get -6y+6y = -2, and the y's disappear. thhe same thing would happen if u substituted -x for y, the x's would disappear.

6x+6y=-2
y=-x
6x-6x=-2
no solution
y=-x
6x-6x=-2
no solution

3x+3y=-1
-3y+3y=-1
There's no solution.
-3y+3y=-1
There's no solution.
