See, make either coefficient of \(x\) or \(y\) just equal to what is that in second equation..
OpenStudy (anonymous):
Firstly, multiply first equation by \(2\)..
OpenStudy (blake57roger):
"If you multiply equation one by 2 you get
2x-4y=12
2x-4y=10"
Since 2x-4y=2x-4y, that implies that 12=10, which is false, so there is no solution.
The lines are parallel.

there is a solution
OpenStudy (anonymous):
So, you will get two equations as :
\[2x - 4y = 12 \\ 2x - 4y = 10\]

Method two:
x-2y=6 --> y=x/2-3
2x-4y=10 --> y=x/2-5/2
Both lines have the same slope but a different intercept, ergo, parallel, and no solution.
OpenStudy (anonymous):
yes^
OpenStudy (anonymous):
As, at the same time, \((2x-4y)\) cannot be equal to \(10\) and \(12\) both, so this means lines are parallel and it is having NO SOLUTION..
