Question

Three students are working to find the solution set of this system of equations:

Answer 1

Answer:

$\{(t,2t-5)\ where\ t\in(-\infty,\infty)\}$ is the solution set.

Step-by-step explanation:

$y=2x-5......(1)\\3y=6x-15........(2)$

Divide eqn(2) by 3.

$y=2x-5$

Hence both are the same lines.

if $x=t$ where $t$ be any point on real line iR.

from eqn (1)

$y=2t-5$

Hence solution set is $=\{(t,2t-5):t \in R)\}$

Answer 2

Answer:

Last one is actually always and infinitely
