multiplying the first equation by 6 and second equation by 4,

3x + 2y = 5 —————->#3

2y + 3x = 5 —————->#4

it’s quite obvious that these equations are the same, so it has infinite solutions.

I suspect this question is wrong.

Yay, my first answer!

8(1/2 x + 1/3 y = 5/6) –> 3x + 2y = 5

-4(1/2 y + 3/4 x = 5/4) –> -2y – 3x = -5

…

um. the results are the same so im stuck.

norm you would multiple the whole equation by a certain number so that you are able to cancel out a variable and hence find the other ..
