It is a deformed round steel bar and has a diameter of 12mm.
The only difference between Y12 and T12 is the Kilos per meter. In a Y12 there is 0.888 Kilos and a T12 bar has 0.612 Kilos.
0.887 kg per m
5X = Y12 ???? If so...., Y12 = 5X Y = 12th root(5X) ===============

if that is suppose to be x3 - y12 then you can not factor this further if that is suppose to be 3x-12y then 3(x-4y) is the factored form
If this is an equation you left out the equal sign. Do you mean y8=y12-4. If so add 4 to both sides. You have 4+y8=y12. Then substract y8 from both sides. You have 4=y4. Divide both sides by 4. You have y=1.
Extreme Steel bar is known as re-bar ( Reinforcing Bar), with two longitudinal and transverse ribs on the diameter of Bar.
