[[5,-7],[-2,3]][[x,y],[z,u]]=[[-16,-6],[7,2]]

Find the matrix X such that , X[{:(5,-7),(-2,3):}]=[{:(-16,-6),(7,2):}] .

If [(x+y,x-y),(7,6)] = [(10,2),(7,z)] then x, y, z are ………… .

If x,y and zinR , and Delta=|(x,x+y,x+y+z),(2x,5x+2y,7x+5y+2z),(3x,7x+3y,9x+7y+3z)|=-16 , then find value of x.

If x,y,z in R & Delta =|(x,x+y,x+y+z),(2x,5x+2y,7x+5y+2z),(3x,7x+3y,9x+7y+3z)|=-16 then the value of x is

If x,y,z in R & Delta =|(x,x+y,x+y+z),(2x,5x+2y,7x+5y+2z),(3x,7x+3y,9x+7y+3z)|=-16 then the value of x is

Find x,y,z using Cramer's Rule,if 5/x-7/y+1/z=11,6/x-8/y-1/z=15,3/x+2/y-6/z=7.

Solve the following equations 5x-7y+z=11, 6x-8y-z=15, 3x+2y-6z=7 by Cramer's rule.

If U = {2, 3, 4, 5, 6, 7, 8, 9} X = {3, 5, 7, 9} Y = {2, 4, 6, 8} Show that X = Y’ and Y = X’
