Yes, xy is the same as yx, but should always be written as xy.
xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
If you're solving for x, then x = 3/y.
To solve the given terms is almost impossible in the absence of any plus, minus and equality signs.
If you mean, "x-3y = 12", then xy = 3y2 + 12y.
If you have a scientific calculator, it should have a key labelled either xy, or yx. Use this for powers.If you have a scientific calculator, it should have a key labelled either xy, or yx.
