It is possible to have more than solution in other types of equations that are not linear but it is also possible to have no solutions or infinite solutions. Moreover the infinite solution has a specific dimension dependening on how the system is constrained by independent equations. Thus suppose we have two equations in two variables as follows.
Write an equation that has infinitely many solutions.
This is what we call this is a consistent system. It is possible to have more than solution in other types of equations that are not linear but it is also possible to have no solutions or infinite solutions. No solution would mean that there is no answer to the equation. Subtracting 25 x from both sides 25 x 25 x 35 25 x 25 x 35 We have -35 -35 which is a True statement it will be true for any value of the variable x.
