Question

Use Gauss-Jordan row reduction to solve the given system of equations. HINT (See Examples 1-6.] (If there is no solution, enter NO SOLUTION. If the system is dependent, express your answer in terms of x, where y = y(x) and 2 = 2(x).) x + y - 22 = 4 X - Y - 52 = 0 (X, Y, 2) - ( -91,64, – 31 ) Need Help? Read It Watch It Talk to a Tutor

Answer 1

Solution to second question using mathematica is

Solution to first part follows

x+y - 22 = 4 -Y -S2 = 0 2x - 7 / 2 = 7 Augmented makinis given by . po 1-2 141 145 0715171 R2 R₂ - R, ; Rom Rz - 2R, l -2 iu To -2 -3 1-4 10 -7 -3/1 27 - R3 R3 5 1/8 R2 ſi 1 -2 4 7 T ó ö l ar 10 -2 -3 | oxton 26843 = 31 30=315 not possible So, given system has no solution)
