  Solving Systems of Equations using Matrices A common application of statics is the analysis of structures, which gen-erally involves computing a large number of forces or moments. For instance, say we would like to determine the tensile or compressive force in each mem-ber of a truss (e.g. a railroad bridge). Applying the basic static equilibrium

  SYSTEMS OF LINEAR EQUATIONS AND MATRICES 1.1.2 Linear Equations in n variables De–nitions We are all familiar with linear equations in two variables, the equation of the line in dimension two. The most commonly used form is the slope-intercept form y = mx+b. However, in this class, we will use the standard form, ax+by = c.

  Provided by the Academic Center for Excellence 3 Solving Systems of Linear Equations Using Matrices Summer 2014 (3) In row addition, the column elements of row “A” are added to the column elements of row “B”. The resulting sums replace the column elements of row “B” while row “A” remains unchanged.

  manner to objects called matrices and various rules for manipulating them. A great amount of time and effort will be spent on matrices, but we always need to keep in mind that we are discussing systems of linear equations. 1.1 Systems of Linear Equations Let’s look at a simple example of a system of linear equations: 2x 1 +3x 2 = 6 −x 1 ...

  Matrices and Systems of Linear Equations Key Definitions Matrix: Numbers written in a rectangular array that are enclosed by square brackets. Order: The size of the matrix. The size is written as × (read “ by ”) where is the number of rows the matrix has and is the number of columns the matrix has.
