-2x-6= -2x-6Another answer:-2x-6 = 2x+6-2x-2x = 6+6-4x = 12x = -3
-2x-6 = 14 -2x = 14+6 -2x = 20 x = -10
I meant 2x+6
6x-y=-14 2x-3y=6
It is a contradiction! 6x - 4x - 6 = 2x 2x - 6 = 2x -6 = 0 false
-2x-6= -2x-6Another answer:-2x-6 = 2x+6-2x-2x = 6+6-4x = 12x = -3
-2x-6 = 14 -2x = 14+6 -2x = 20 x = -10
I believe the converse is: if 2x equals 6 then x equals 3 inverse: if x doesn't equal 3 then 2x doesn't equal 6 contrapositive: if 2x doesn't equal 6 then x doesn't equal 3
I meant 2x+6
x=1
6x-y=-14 2x-3y=6
It is a contradiction! 6x - 4x - 6 = 2x 2x - 6 = 2x -6 = 0 false
2x+3y = 6 2x+3(0) = 6 2x = 6 x = 6/2 x = 3
2x=6 /2=/2 x=3
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
If: y = x+6 and y = 2x Then: x+6 = 2x And: 6 = 2x-x => 6 = x So: x = 6 and y = 12
6 + 2x = x - 6 2x - x = -6 -6 x = -12
