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
I meant 2x+6
7/2x = 3 Multiply both sides by 2x: 7 = 3*2x = 6x Divide both sides by 6 = 7/6 = x ie x = 1.1666...

2x/3=x/2+20 (2x/3=x/2+20)6 4x=3x+120 4x-3x=120 x=120
2x + 4 = 6/x - 3 ∴2x - 6/x + 7 = 0 ∴2x2 + 7x - 6 = 0 X ∈ {0.71221447, -4.2122145}
-2x-6= -2x-6Another answer:-2x-6 = 2x+6-2x-2x = 6+6-4x = 12x = -3
4x-6 = -2x-3 4x+2x = 6-3 6x = 3 x = 3/6 = 1/2
2x-3+12= 6 move the +12 over to become -12 2x-3=(6-12= -6) then move -3 over so it becomes +3 2x=(-6+3= -3) then take the two over so you divide by two x=(-3 divided by 2= -1.5) so x = -1.5
2x + 3 = 6 2x = 3 x = 3/2 = 1.5
2x+3y = 6 2x+3(0) = 6 2x = 6 x = 6/2 x = 3
if 2x+3=9 then 2x=6 so x=3
2x=6 /2=/2 x=3
