This is a simple equation and can be solved very easily. This is an equation that has only one unknown and that is x. If these kind of problems have more than 1 unknown or rather 2 unknown, then there has to be two equations to solve those problems. the number of unknowns are directly dependent on the number of equations. These are small but technically correct problems to improve the sense of calculation.
24x = -12
x = - (12/24)
= -1/2
The unknown number x is -1/2
