The solution to the homogeneous equation is. By substitution you can verify that setting the function equal to the constant value -c/b will satisfy the non-homogeneous equation. It is the nature of differential equations that the sum of solutions is also a solution, so that a general solution can be approached by taking the sum of the two solutions above.

If a solution exists, the system is consistent; if not, it is inconsistent. A system of linear equations can be represented by a matrix whose elements are the coefficients of the equations. Though simple systems of two equations in two unknowns can be solved by substitution, larger systems are best handled with matrix techniques. You substitute this expression into where that equation has the letter y. And now I have one equation with one variable it only has x, and that's something I know how to solve. Either way no matter how you chose to solve this system of equations with substitutions, please make sure your answer is a point.Jan 06, 2016 · After the students had an understanding of writing, solving and interpreting systems of equations using multiple representations, I taught the students how to solve algebraically (setting the equations equal).
