I am to solve this system of equations x+3y=8

x=4-3y

I got (2,2), but I am not sure if this is righ, can you help me?

  • algebra -

    Try substituting (2, 2) into both equations to check if they hold.

    It is possible for a system of equations to have no solution.

  • algebra -

    I am gathering there is no solution because in the second equation it would not be 2 it would be -2...am I right?

  • algebra -

    Yes.

    You can rearrange the equations to get
    x + 3y = 8
    x + 3y = 4

    In that form, there is obviously no solution.
