What is the simultaneous equation for 2x plus 5y equals 20?

Another straight line equation is needed such that both simultaneous equations will intersect at one point.

How many solutions do the following equations have in common 8y equals -75x - 22 and 75x equals -8y plus 22?

I notice that the ratio of the y-coefficient to the x-coefficient is the same in both equations. I think that's enough to tell me that their graphs are parallel. So they don't intersect, and viewed as a pair of simultaneous equations, they have no solution.

What is the solution of the system of equations 3x plus 6y and ndash2 15x plus 30y and ndash10?

Without any equality signs the given expressions can't be considered to be simultaneous equations and so therefore no solutions are possible.
