None because without an equal it is not an equation. But if it was in the form of x2+7x+12 = 0 then it would have 2 solutions which are x = -3 and x = -4
You would set the equation equal to 0 and then solve for x. You may get one or several answers for x, x being the number(s) that make the equation equal 0.
An example of an equation that will always equal 12 is x=12. x will never change and will always be equivalent to 12.
If x = 8 satisfies the equation 19 - x = 12, then it is a solution of the equation. 19 - x = 12 19 - 8 = ? 12 11 ≠ 12 Since x = 8 does not satisfy the equation, x = 8 it is not a solution.
2 x 2 x 3 = 12
15 percent of the number 80 is equal to 12. The equation for this problem would be X x 15% = 12.

Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)
Equation: x+3=3+x (notice the equal sign: equal; equation)Expression: x+3 (notice no equal sign)
You would set the equation equal to 0 and then solve for x. You may get one or several answers for x, x being the number(s) that make the equation equal 0.
