Consider the following simple 2x2 systemof linear equations a11 x1 + a12x2 = b1 (7) a21 x1 + a22 x2 = b2 We can write this in matrix form as Ax= b A = a11 a12 a21 a22 ,x= x1 x2 ,b= b1 b2 . SYSTEM OF FIRST ORDER DIFFERENTIAL EQUATIONS If xp(t) is a particular solution of the nonhomogeneous system, x(t) = B(t)x(t)+b(t); and xc(t) is the general solution to the associate homogeneous system, x(t) = B(t)x(t) then x(t) = xc(t)+xp(t) is the general solution. If you graph the given equations using their slope and y-intercept, you will find two lines. These equations may have more than one of the same variable on each side of the equal sign −5 = 4+ 7. and/or may contain parentheses 3(4−2) = 5(+ 3) MEDIA LESSON General Equations (Duration 5:00) View the video lesson, take notes and complete the problems below .
