Write the system as a vector equation or matrix equation as indicated. Write the following system as a matrix equation involving the product of a matrix and a vector on the left side and a vector on the right side. 2x1 x2 - 5x3

Step-by-step explanation:

The complete system of equations are:

From above; the equation can be re-written as:

;

However; writing the system as a matrix equation in form:

where;

A = coefficient matrix ; = variable vector ; and, = constant vector

Then:

The coefficients of

The coefficients of

The coefficients of

∴

Finally;

the coefficient of matrix A =

equal to
