3 - 6X = 4X + 9
subtract 4x from each side
3 - 10X = 9
subtract 3 from each side
- 10X = 6
divide each sides integers by - 10
(- 10/- 10)X = 6/- 10
X = - 3/5
==========check in original equation
3 - 6(- 3/5) = 4(- 3/5) + 9
3 + 18/5 = - 12/5 + 9
now, 3 = 15/5 and 9 = 45/5
15/5 + 18/5 = - 12/5 + 45/5
33/5 = 33/5

6x - 4y
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
-1 + 4x + 6x - 20 =10x - 19
x = 2
6x + 34 = 4x +284 6x - 4x = 284 - 34 2x = 250 x = 125
6x - 4y
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
-1 + 4x + 6x - 20 =10x - 19
x = 2
6x + 34 = 4x +284 6x - 4x = 284 - 34 2x = 250 x = 125
3+6x = 4x+9 6x-4x = 9-3 2x = 6 x = 3
this is the same as 6x - 2 = 6x - 2! There are an infinite number of possibilities for "x".
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
4x+6y=62 -6x+6y=-18 what is the ordered pair
6x + 10 + 4x = 5010x + 10 = 5010x = 40x = 4
x = 0,1
