    perhaps multiply equation 2 by a factor of 2 and see what you get

    first: multiply the second equation by 2 and post the result here...

    I'd say, solve each equation for "y" so you can see their slope same slopes, no solutions since they're parallel different slopes, one solution

    ok - that's correct so if you look at the first equation 2x + 6y=5 and your equivalent to the seconf 2x+6y=4 then you can see that they cannot BOTH be true for the same values of x and y therefore there is no solution to th e'system' the lines do not intersect
