If `A={:[(1,2,3),(3,-2,1),(4,2,1)], X={:[(x),(y),(z)]and B={:[(6),(2),(7)]` write down the linear equations represented by AX = B.

if A= [[1,2,3],[3,-2,1],[4,2,1]] X= [(x),(y),(z)] and B= [(6),(2),(7)] .Write down the linear equation represented by AX = B.

Given A = [(1,2,3),(3,-2,1),(4,2,1)] , X = [(x),(y),(z)] and B = [(1),(2),(3)] Write down the linear equations given by AX = B.

If A={:[(1,2,3),(2,-1,5),(-3,2,4)],X={:[(x),(y),(z)]and B={:[(14),(15),(13)] then write down the linear equations in x, y, z represented by the matrix equation AX = B.

Given A = [(1,1,1),(2,-1,1),(2,1,-3)] , X = [(x),(y),(z)] and C = [(3),(-1),(-9)] Write down the linear equations given by AX = C and solve for x, y,z by method.

x/3 + y/2 =1 in this equation represent x as a function of y.

If A = [(1,2,3),(1,3,-1),(-1,1,-7)] , find A^(-1) , hence solve the following system of linear equations: x + y - z = 3 , 2x + 3y +z 10 and 3x - y - 7z = 1

If A={:((x,-2),(2,1)),B={:((3,4),(0,1)),C={:((-1,-2),(y,2)) and A + B = BC. find x and y.

If A = [(1,2,-3),(2,3,2),(3,-3,-4)] , find A^(-1) and hance solve the system of linear equations: x + 2y - 3z = -4, 2x + 3y + 2z = 2, 3x - 3y -4z = 11

Use product {:[( 1,1,2),( 0,2,3),( 3,2,4) ]:} {:[( 2,0,1),(9,2,3),(6,1,2) ]:} to solve the system of equations x-y+2z=1 xy-3z=1 3x-2y+4z =2

Write the direction cosines of the line 6x-2=3y+1=2z-4 .
