The first step for solving the solution is to change the ~y variable in the form of triangular fuzzy numbers so that the parameters from triangular fuzzy numbers obtained. The next step is to change n n matrix A into 2n 2n matrix S and by using the inverse method, so that the triangular fuzzy solution obtained is changed to the trapezoidal fuzzy solutionotherFuzzy linear systemtrapezoidal fuzzy linear systemtrapezoidal fuzzy numberstriangular fuzzy numbersOther
