Question

Determine if the statement is true or false. A system in echelon form can have more variables than equations. True False

Answer 1

True.

Explanation:

A system of a mathematical expression such as a matrix is said to be in echelon form when it has many variables.

There are two (2) forms of echelon matrices and these includes;

I. Reduced row echelon form (RREF)

II. Row echelon form (REF)

Hence, a system in echelon form can have more variables than equations.
