Answer:

[tex]\{(t,2t-5)\ where\ t\in(-\infty,\infty)\}[/tex] is the solution set.

Step-by-step explanation:

[tex]y=2x-5......(1)\\3y=6x-15........(2)\\[/tex]

Divide eqn(2) by 3.

[tex]y=2x-5[/tex]

Hence both are the same lines.

if [tex]x=t[/tex] where [tex]t[/tex] be any point on real line iR.

from eqn (1)

[tex]y=2t-5[/tex]

Hence solution set is [tex]=\{(t,2t-5):t \in R)\}[/tex]

Answer:

Last one is actually always and infinitely
