xy + x + y + 1 is an expression, not an equation. An expression cannot be solved.
Yes, xy is the same as yx, but should always be written as xy.
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.

To solve the system of equations given by ( xy = x + 2y ) and ( xy = x - z ), we can start by equating the two expressions for ( xy ). Setting ( x + 2y = x - z ) gives us ( 2y + z = 0 ) or ( z = -2y ). Substituting ( z ) into the other equation leads to a system that can be solved for ( x ) and ( y ). However, without numerical values or additional equations, we cannot find unique solutions for ( x, y, ) and ( z ).
