Consider the linear system -3, - 682 + 1x2 - 8x4 = 9 0 - 2x - 4X2 - 2X3 +0 N = 6 0 ox, tox2 - 2x3 + 4 X = 0 6 Now, 2 x 0 and 3x® and subtracting each other we get -64, - 18x2 +2%3-1644 =18 Foor, Y2K2 - xy +0.81, 18 883-1844 = 0 or - h (-223 + 424)=0 or B-242 +42 = 0 , which is equation ③ Independent rystem of linear equation are -30 - 6H2 + 128-8X4 = 9 -24 - 4Hq - 2 z tox=6 let, t = a, dq=bed where a bEIR then -3a, 66, + X3-8 du = 9 or, xz - 8x4 = 9+30+66, - and -20 - 46,- 2 X ₂ H OH = 6 or - 2x3 = 6 +24thb, for X=-3-0-26 6
Then from Nz-844 = 9+3at. 66, or, -8 ky = 9+39 +66,- K3 or -8X4 = 9+30+66, +3 +4 +26, or, -8X4 = 12 that 86, or, -224 = 3tą +26, or, Ny = - 3 2 - a - bi q = 6, Az = -3 -2 -26, xu = - 3 2 - a - b In 72 -3-a,-261 1 Nio-a ng و هل حدادم nen
