Answer 1

Q2 MATLAB CODE:

%We can write the given four equation in the form AX=B
%The A matrix is a 4*4 Matrix (By taking respective coefficients)
A=[2 1 -1 2;4 5 -3 6;-2 5 -2 6;4 11 -4 8]
%The B matrix is a column matrix(By taking respective coefficients)
B=[5;9;4;2]

%solving by using 2 methods
SOL1=inv(A)*B %solving by using the inverse function
SOL2=A\B %Solving by using \ operator. This is faster in computation
