Sample Problem

Solve the following linear system. If there are no solutions, put “ns” for the x and y coordinate

3x – 2y = 5

-6x + 4y = 1

x = y =

Solution

(3x – 2y = 5) × 2 → 6x – 4y = 10

-6x + 4y = 1

6x – 4y = 10

-----------------

0 = 11

This equation is never true, so there are no solutions to this equation.
