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

2x + 4 = 10 2x = 10 - 4 = 6 2x = 6 x = 6/2 = 3
6 2(6) + 3 = 9
2x + 7 = 1 Therefore, 2x = -6 x = -6/2 x = -3
6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
2x - 4 = -10 2x = -10 +4 2x = -6 x = -3
