1. 4x-12=4x-12, then 0=0. This equation has infinite amount of solutions;
2. 4x-12=3x-4,4x-3x=-4+12,x=8. This equation has one solution.
3. 4x-12=3(2x-6),4x-12=6x-18,4x-6x=-18+12,-2x=-6,x=3. This equation also has one solution.
4. 4x-12=4(x-5),4x-12=4x-20,4x-4x=-20+12,0=-8 is not right equality, then this equation hasn't solutions.
