Linear System - Write As A Matrix

Linear System - Write As A Matrix

Lesson 1

Problem: Write the linear system as a matrix equation.

6x + 9y = 81

6x + 5y = 44

Step 1: Write the coefficients of x in the first column of first matrix.

Solution Write the coefficients of y in the second column of first matrix.

Step 2:

Solution Write x, y in the second matrix column wise.
