Such questions essentially are asking you to find all solutions of an equation, and should any imaginary solutions (containing the imaginary number 'i') come up, to discard these solutions. Therefore, most of the time, you will approach both equations with only real solutions and equations with both real and imaginary solutions the same way: find the solutions, and discard the ones that are ...

But with differential equations, the solutions are functions. In other words, you have to find an unknown function or functions, rather than a number or set of numbers as you would normally find with an equation like f(x) = x 2 + 9. For example, the differential equation dy⁄dx = 10x is asking you to find the derivative of some unknown function y that is equal to 10x. Differential equations ...

If solutions start “near” an equilibrium solution will they move away from the equilibrium solution or towards the equilibrium solution? Upon classifying the equilibrium solutions we can then know what all the other solutions to the differential equation will do in the long term simply by looking at which equilibrium solutions they start near.

So this is one solution, just like that. Now if you go and you try to manipulate these equations in completely legitimate ways, but you end up with something crazy like 3 equals 5, then you have no solutions. And if you just think about it reasonably, all of these equations are about finding an x that satisfies this. And if you were to just ...

**Equation Solver - MathPapa**

Given a linear equation of n variables, find number of non-negative integer solutions of it. For example,let the given equation be “x + 2y = 5”, solutions of this equation are “x = 1, y = 2”, “x = 5, y = 0” and “x = 1. It may be assumed that all coefficients in given equation are positive integers.

Solving a linear Diophantine equation means that you need to find solutions for the variables x and y that are integers only. Finding integral solutions is more difficult than a standard solution and requires an ordered pattern of steps. You must first find the greatest common factor of the coefficients in the problem, and then use that result to find a solution. If you can find one integral solution to a linear equation, you can apply a simple pattern to find infinitely many more.

The basic idea behind solving by graphing is that, since the (real-number) solutions to any equation (quadratic equations included) are the x-intercepts of that equation, we can look at the x-intercepts of the graph to find the solutions to the corresponding equation. However, there are difficulties with "solving" this way. When we graph a straight line such as "y = 2x + 3", we can find the x ...

An identity is an equation that is always true, independent of the value(s) of any variable(s). For example, you might get an equation that looks like x = x, or 3 = 3. This would tell you that the system is a dependent system, and you could stop right there because you will never find a unique solution. 3. Inconsistent Equations
