Tasked with solving the system of equations

solve the system of equations :

5x + 3y - 8z + 16w = -21

6x + 8z - 20w = 18

7x + 9y + 12z - 8w = 15

16y + 11z + 8w = 10

syms x y z w
RC = @() randi([-25 25]);
eqn1 = RC()*x + RC()*y + RC()*z + RC()*w == RC()

eqn1 = 

eqn2 = RC()*x + RC()*y + RC()*z + RC()*w == RC()

eqn2 = 

eqn3 = RC()*x + RC()*y + RC()*z + RC()*w == RC()

eqn3 = 

eqn4 = RC()*x + RC()*y + RC()*z + RC()*w == RC()

eqn4 = 

eqns = [eqn1;eqn2;eqn3;eqn4]

eqns = 

vars = [x, y, z, w];

[A,b] = equationsToMatrix(eqns, vars)

A = 

b = 

vars(:) == A\b
