Solving Systems of Equations by Elimination: SMART Board Resource for Algebra (Grades 6-12) (eLesson Plan)
We first encountered Gaussian elimination inSystems of Linear Equations: Two Variables. In this section, we will revisit this technique for solving systems, this time using matrices.
Differential equations are equations where rates of change occur with respect to variables. Learn how to solve systems of linear differential...
Applications of Systems of Equations Now we will turn to the applications for which systems of equations are used. In the next example we determine how much money was invested at two different rates given the sum of the interest earned by both accounts. ...
To solve systems using Substitution: Step #1: Check to see if one of the equations has a variable alone Step #2: Substitute what that variable equals into the other equation Step #3: Solve for the other variable Step #4: When you know what one variable is, plug it back in to find ...

x=1 This value of x can then be used to find y by substituting 1 with x e.g. in the first equation y=2x+4 y=2⋅1+4 y=6 The solution of the linear system is (1, 6). You can use the substitution method even if both equations of the linear...

One of the last examples on Systems of Linear Equations was this one:Example: Solve x + y + z = 6 2y + 5z = −4 2x + 5y − z = 27We went on to solve it using "elimination", but we can also solve it using Matrices!
