Question

Please discuss the graphic system, substitution system and elimination system. Which one do you think it is easier and why?

This is intermedia algebra, we are talking about graphs and solve for the for adding and subtraction and solve for the substitution method.

Answer 1

to infinitely many Graphice system - In this we draw une Corresponding the equations and of une coonude we have sclunun of the intersect at one point then it has unique solution and of the parallel there is no solution. (In 3 dimensional we can get regions also ) Unes are Substituted Method one the same we In this method we calculare value of varvable in terms of another variable wong one equation. Laren substitute value in anomer equarn on this way we can solve the equarn. Elimination method In this one vanable me this way and we vains gr we try to elemenare Surable multiplican of scalars and adding or substraing the equations, an We are left with one of variable only can easily evaluan of evaluan of The put above equans to get value of other vanable. Elmination murhod is easur as grape sygen is hard to Judge exact pont live irrational Where as in substitution method # the expression can be long and the cause computaruns number ) im difficulty
