Question: Which of the following statement is false? If A and Bare matrices and AB and BA are both defined, then we can conclude that A = B. The expression AX = B is the matrix form corresponding to a system of linear equations if matrix A is the coefficient matrix, the vector X is the column vector of variables and B is the column vector constructed from the constants. When the number of columns in matrix A equals the number of rows in matrix B, then we can obtain the product of AB. Associative law of addition states that for each matrix A, B and C: (A+ B) +C = A+ (B +C)

Guided Proof Prove that if A is row-equivalent to B, and B is row-equivalent to C, A is row-equivalent to C. Getting Started: to prove that If A is row-equivalent to C, you have to find elementary matrices E1, E2. Ek such that A=EkE2E1C. i Begin by observing that A is row-equivalent to B and B is row-equivalent to C. ii This means that there exist elementary matrices F1F2Fn and G1G2Gm such that A=FnF2F1B and B=GmG2G1C. iii Combine the matrix equations from step ii.
