    Right, So how exactly? Do you make 1/2 to just 2?

    lets go slow again you want to get rid of the fraction right? so that the coefficients are "integers"

    you got \[y=-\frac{1}{2}x-3\]

    to get rid of the two in the denominator, multiply both sides by \(2\) \[2\times y=2\times (-\frac{1}{2}x-3)\]

    hmm looks like you forgot the distributive property you also have to multiply \(-3\) by \(2\)

    a common mistake actually now on the right, it was \(-6\) so it is still \(-6\)

    \[x+2y=-6\] in other words
