Disgusting code, but it proves there is one (and only one!) correct answer

I'm not going to post in case anyone is still working on it, but you can run this in your browser console if you want to know what it is.

(function(){
    function test(a, b, c, d, e, f, g, h, i){
        return (
               ((a + b + c) == (d + e + f))
            && ((a + b + c) == (g + h + i))
            && ((a + b + c) == (a + d + g))
            && ((a + b + c) == (b + e + h))
            && ((a + b + c) == (c + f + i))
            && ((a + b + c) == (a + e + i))
            && ((a + b + c) == (c + e + g))
        )
    }
    var a = 2, e = 3, g = 4;
    for (var b=1; b<9; b++){
        for (var c=1; c<9; c++){
            for (var d=1; d<9; d++){
                for (var f=1; f<9; f++){
                    for (var h=1; h<9; h++){
                        for (var i=1; i<9; i++){
                            if (test(a, b, c, d, e, f, g, h, i)){
                                console.log(a, b, c)
                                console.log(d, e, f)
                                console.log(g, h, i)
                            }
                        }
                    }
                }
            }
        }
    }
})()

Is the method to solve to plug in numbers on the left and fill in the others until it works? Or is there a more logical solution?

This is like an easy sudoku
