There is no real number division by zero in mathematics.
This is a singularity.
The reason is, if division by zero was possible, all numbers would be equal to all numbers and number theory, the foundation of mathematics, would collapse.
ujue mmeshindwa kutambua theory za math,any numba over zero is undifined(undifined means anythin can hold or u can easly say any namba is the answer) ze soln is right hapo ni sawa na ukiambiwa solve simultaneously 2x+4y=8 and x+2y=4.te te te math bwana
