6 + 2x = x - 6 6 + x = -6 x = -12
-17-2x=6-x -23=x
2x+3y = 6 2x+3(0) = 6 2x = 6 x = 6/2 x = 3
2x - 6 = x + 5 Isolate x. 2x - x = 6 + 5 x = 11
4x+9=2x-6 2x=-15 x=-7.5 x equals -7.5.
6 + 2x = x - 6 2x - x = -6 -6 x = -12
If: y = x+6 and y = 2x Then: x+6 = 2x And: 6 = 2x-x => 6 = x So: x = 6 and y = 12
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
6 + 2x = x - 6 6 + x = -6 x = -12
-17-2x=6-x -23=x
2x+3y = 6 2x+3(0) = 6 2x = 6 x = 6/2 x = 3
2x - 6 = x + 5 Isolate x. 2x - x = 6 + 5 x = 11
4x+9=2x-6 2x=-15 x=-7.5 x equals -7.5.
2x-6=x+5 2x -x=6+5 x=11 Check the math.
-2x-6 = 14 -2x = 14+6 -2x = 20 x = -10
x=1
2x -6 = 4 then 2x = 4 +6 x=10/2 = 5
