None because without an equality sign the given expression is not an equation.
x2 - 12x + 35
That looks like a linear equation (no quadratic or higher terms), so you can expect it to have a single solution. However, actually solving the equation is not difficult; do it, to confirm this.
It is x = +/- 2 depending on whether the second term in the equation is -12x or +12x.
Unfortunately, the browser used for posting questions is hopelessly inadequate for mathematics: it strips away most symbols. As a result there is no equation in the question and so there can be no answer. It makes little sense for me to try and guess - I may as well make up my own questions and answer them!

x2 - 12x + 35
Only one. 2x - 12x = 220 -10x = 220 x= 220/-10 x = -22
Just the one because if: 12x+6 = 5x then x = -6/7
Since that isn't an equation, there is really nothing to solve.

2.72 and 0.28 This is not an equation, so it cannot be solved.
2y-12x=-6 is the equation of a line. It has infinite number of solutions which are all the points one the line. We can rewrite the equation as 2y=12x-6 and then divide both sides by 2.This gives us y=6x-3. From this we know the equation describes a line with y intercept -2 and slope 6.
Taken literally as...-0.2x + 12x + 11 = 0 (assuming nothing was lost during the question-asking process)...this equation as exactly one solution:-0.2x + 12x = -11x(-0.2 + 12) = -11x(11.8) = -11x = -11/11.8 = -110/118 = -55/59 = -0.9322

That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: (-2 plus or minus the square root of 5) divided by 3x = 0.07868932583326327x = -1.4120226591665965
That doesn't factor neatly. Applying the quadratic equation, we find two real solutions: 3 plus or minus 0.5 times the square root of 14 x = 4.87082869338697 x = 1.1291713066130293
