The equations are inconsistent.
If you divide the first equation by 2, you get
y + 4x - 6 = 0
or 4x + y - 6 = 0
or 4x + y = 6
The second equation, however, gives
4x + y = -6
The two equations, taken together would imply that 6 = -6 which is false.
many solutions
4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
Two solutions and they are:- x = 0 and y = 3
-2
Both of them are equations!The solution is (x, y) = (2, 1).

4y+4 = 2y+12 4y-2y = 12-4 2y = 8 y = 4
If: 3x+2y = 5x+2y = 14 Then: 3x+2y = 14 and 5x+2y =14 Subtract the 1st equation from the 2nd equation: 2x = 0 Therefore by substitution the solutions are: x = 0 and y = 7
Two solutions and they are:- x = 0 and y = 3
-2
Both of them are equations!The solution is (x, y) = (2, 1).
what is the slope of the line that has the equation 4x+2y=12?
4
-65
2x+y=-12-4x-2y=30 x=-y/2+30, you plug this into -12-4x-2y=30 and get -12+2y-120-2y=30 which gives 2y-2y=162. This is not possible, so the equation is unsolvable.
Y= 1/4.
