-3x + 4x = 12
x = 12
A graph normally shows the relationship between two interconnected quantities,
such as 'x' and 'y' .
This equation can't be graphed. There's only one quantity ... 'x' . It doesn't depend on any
other quantity, and no other quantity depends on 'x'.
'x' is 12, it's always 12, and it doesn't change, and that's the whole story.
The lines are parallel.
2x-12
3x+8 = 12 3x = 4 x = 4/3
3x+42=6x+12 42=6x-3x+12 42=3x+12 42-12=3x 30=3x 10=x
Point slope equation: Y=3X+12

3x+12=x+48: 3x-x=-12+48 2x=36 x=18
3x - 12 = -2x + 235x = 35 so x = 7
7x = 3x - 12 4x=-12 x=-3
3x + 4y - 4 = 0 y = -2 3x + 4(-2) - 4 = 0 3x - 8 - 4 = 0 3x = 12 x = 4 (4,-2)
No.
y-3x+6y=12 7y=3x+12 y=3x/7 +12/7
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
