It doesn't; it equals 2x. Only if x = 0 does 2x = x.
It is: 12x
If x is equal to 5, then x squared plus 25 is equal to 50.
It equals x+5y simplified
Yes it does
-x + x = 0.
X plus 7-12?
no...why would it.... it equals 2x+9
One plus cosecant squared x is equal to cotangent squared x.
x = 0
X 3 plus x-142 plus x is an equation equal to x3+2x-142.
x+x=2x
(x + 3)(x + 4) = x2 + 7x + 12
