How do you solve the system using matrices.

-x+2y=1.5

2x-4y=3

Expert Answers

An illustration of the letter 'A' in a speech bubbles

We have the simultaneous equations

-x + 2y = 1.5 ...(1)

2x - 4y = 3 ...(2)

Looking at the two matrices we see that 2*(1) = -2x + 4y = 3

=> 2x - 4y = -3

Comparing to (2) we see that 2x - 4y = 3 and 2x - 4y = -3

This is not possible. Therefore it is not possible to solve the equations. There is no use of using the matrix method as it would not yield a solution

The set of equations cannot give a solution.
