No solution

Explanation:

Change the second equation so that it is set equal to y:

y2x=5y=2x5

Then set the two equations equal to each other (equal values method):

2x3=y=2x5

2x3=2x5

Subtract 2x on both sides:

3=5

This is a false statement, so there is no solution.

These two equations have no points in common, it can be shown visually as two parallel lines that never intersect:

There is no solution. They are parallel lines.

Explanation:

2xy=3
2x+y=5 Add the two equations.
0=2 NO SOLUTION
