Abstract
In this expository paper we discuss the solution of trapezoidal fuzzy linear system
A~x =y with ~x and ~y which the vectors of trapezoidal fuzzy numbers developed
from a paper by Nasseri and Gholami [3]. 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 solution
