how to solve these simultaneous equations

hi there!

i have a simple question about solving equations

i have matrix "Y" and "d" which contain unknowns

size(Y)=size(d)=[ 2 , 1 , 30 ];

and i have a matrix "X" which contains knowns size(X)=[ 2 , 1 , 30 ];

and i would like to solve the equations as below

for k = 1 : 30 ;

    d(:,:,k)/2+Y(:,:,k)=X(:,:,k);
end;

how can i solve these simultaneous equations???

thank you!

You cannot. Every equation contains 2 distinct unknowns, and therefore your total system has twice as many unknowns as equations. Moreover, the equations are also not "simultaneous" in any meaningful way, since no unknown appears in more than one equation.

i am sorry i didn't say that matrix Y contain unknowns about d

so i am sure there are sufficient equations to solve the unknowns

can i use "solve" here and how can i use it?

thank u!

You should tell us more about the dependence of Y on d.
