Document Summary
21 x t 212 2 t 213 3 a o an xn where i 212 213 o are constants. 21 and are called the coefficients is called the constant term or the right hand side examples. Example write the augmented matrix matrix whose rows the coefficient rows of the for the following equations systems are x. Example write the augmented matrix for the following system y. Example system and keep track of augmented matrices as you work through the solution. Elementry row operations these do not change the solution 1st of the system of equations. Type 1 replacing r by a r where a. Type 3 switching the order of the rows. Step 1 clear the fractions if any and or decimals by using type 1 operations. Step 2 designate the first entry in the first the pivot always nonzero row as put a box around your pivot.
