The question doesn't include:
-- the other equation[s] in the 'system' of equations
-- anything to substitute
Either one or the other is necessary in order to find a solution.
There are two solutions and they are: x = -1 and y = 3
When (the graph of the equations) the two lines intersect. The equations will tell you what the slopes of the lines are, just look at them. If they are different, then the equations have a unique solution..
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.
A pair of simultaneous equations in two unknowns which are inconsistent - in the sense that there is no solution that simultaneously satisfies both equations. Graphically, the equations are those of two parallel lines (slope = 2). Since, by definition, they cannot meet there is no solution to the system.
x = y = 3
{-1,-2}
If "equations-" is intended to be "equations", the answer is y = -2. If the first equation is meant to start with -3x, the answer is y = 0.2

No.
The graphs of those two equations are straight lines, each of which passes through the origin. The origin is the common solution ... the point (0, 0).
