2x = x+3 2x-x = 3 x = 3
x + 3 = 2x 3 = x x cannot be 2
2x=x+3=x=3
2x = 4x + 3 -2x = 3 x = -3 / 2
2x+3=9 2x=9-3 2x=6 2x/2=6/2 X=3
2x = x+3 2x-x = 3 x = 3
2x + 3 = x 2x + 3 - 3 = x - 3 2x = x - 3 2x - x = x - 3 - x x = -3
x + 3 = 2x 3 = x x cannot be 2
2x=x+3=x=3
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 = 4x + 3 -2x = 3 x = -3 / 2
2x+3=9 2x=9-3 2x=6 2x/2=6/2 X=3
2x-3 = x+5 2x-x = 8 x = 8
2x+3=9x 3=9x-2x 3=7x x=3/7
2x-3=x+2 2x-x=2+3 x=5
x squared -2x-3 equals 0 is the same as (x + 1)(x - 3) = 0
x+3(x+1)=2x x + 3x + 3 = 2x 2x + 3 = 0 2x = -3 or x = -1.5
