How to solve the following questions?

A =[1;1;2]

B= [x y 6;x y 5; x y 4]

C = [2;3;4]

D = B*C

I want to write a code so that that multiply the matrix B (of some unknown variables) with matrix C, SO as D(1) be = x*2+y*3+6*4 D(2) be = x*2+y*3+5*4 D(3) be = x*2+y*3+4*4

and then A = D

so that , A(1) = D(1) & A(2) = D(2) & A(3) = D(3).

Now using the solve command i will solve the value of x & y.

Can anyone,help me please?

Your system is equivalent to:

[2 3;2 3;2 3]*[x;y] = [-23;-19;-15]

What makes you think this has a solution?
