How many solutions are possible for 2x equals 2y plus 2 and 2y equals 2x plus 2?

Answer 1

There are 0, or no solutions to these equations. If you rearrange each equation to look like an equation of a line, you will have the two lines:

y = x -1 and y = x + 1, which are two parallel lines. They do not intersect at any point, so there is no solution.
