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
y=2x-3 y=-x-3
That completely depends on the value of 'x', and whenever the value of 'x' changes, [ 2x + 2 ] also changes immediately.
You can look up "trigonometric identities" in Wikipedia.Cos(2x), among other things, is equal to (cos x)^2 - (sin x)^2 If you meant cos squared x, or (cos x)^2, that is equal to (1 + cos(2x))/2
4x+3y-2x+y 4x-2x+3y+y 2x+4y Taking out 2 common 2(x+2y) Hence the required answer is 2(x+2y)
x+x=2x
2x minus 3x is equal to -x.

It doesn't; it equals 2x. Only if x = 0 does 2x = x.
only when x is equal to 2
There is insufficient information to answer this question. If you mean, what does x equal for: 9 + 6x = 2x ...then the answer is: 9 = 2x - 6x = -4x ...which is equal to: x = -9/4 If you mean, what does x equal for: 9 + 6x + 2x = 0 ...then the answer is: 8x = -9 ...which is equal to: x = -9/8
y=2x-3 y=-x-3
2x minus 3x is equal to -x.
x+3(x+1)=2x x + 3x + 3 = 2x 2x + 3 = 0 2x = -3 or x = -1.5
X + ( 2Y - 2X - Y ) is equal to Y - X
x2 - 2x = x(x-2) and that cannot be simplified further.
Only if x is equal to 2.
