x=(y-3)/2
The multiplicative inverse of 3+2x is 1/(3+2x).
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 + 3)(2x + 3)
4x + 3 = -3 + 2x + 14 2x + 3 = -3 +14 2x + 3 = 11 2x = 8 x=4
2x = x+3 2x-x = 3 x = 3
(0, -3)

the converse of this conditional is true
if 2x+3=9 then 2x=6 so x=3
2x = 4x + 3 -2x = 3 x = -3 / 2
2x=x+3=x=3
