A system of equations has no solution when the lines representing the equation are parallel but do not coincide. For two lines to be parallel, the must have the same gradient i. e. coeficient of x when y is made the subject of formular must be equal.

If one of the equations is y = 8x + 7, then the other equation will be y = 8x - 7
