Question

What are the solutions of the following system?


`\left \{ {{x -2y = -6} \atop {-2x + 4y = -3}} \right.`

Answer 1

Explanation:

x-2y=-6 ...(1)

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

Multiply equation (1) by 2

So,

2x-4y=-12 ...(3)

Now add equation (2) and (3).

-2x+4y + 2x-4y = -3+(-12)

0=-15

It means that there is no solution of the given equations.
