2. 3. 1.. x*1 = 2 x*2 = 3 x*3 = 1. 1.6 Linear Dependence and Determinants. Suppose we have the following. 1. x1 + 2x2 = 1. 2. 2x1 + 4x2 = 2 where equation ... 2x1 + x2 − x3 = 6 x1 − 2x2 −2x3 = 1. −x1 + 12x2 +8x3 = 7. 4) Solve, using Gaussian elimination, x1 +2x2 +4x3 = 1 x1 + x2 +3x3 = 2. 2x1 +5x2 +9x3 = 1. 5 ... then x1 = 1−2x2 = 1−2t. Therefore, the solution set is (x1,x2) = (1−2t, t) = (1, 0) + t(−2, 1) for arbitrary t; this is the parametric equation of a ... x1 - 5x2 + 4x3. = -3. 2x1 - 7x2 + 3x3. = -2. -2x1 + x2 + 7x3. = -1. 4. Consider the following system of linear equations x1-2x2-2x3 = 2 x1+2x2+ x3 = 3. 3x1+2x2. ... X1 - 2X2 * * xn).
