I have a question I have this systems to solve

2x-y = 1

How do I go about solving this?
Please give me some direction

  • Algebra -

    sub the 2nd into the 1st

    2x - y = 1
    2x - (3x-3) = 1
    2x - 3x + 3 = 1
    -x = -2
    x = 2

    back into the 2nd
    3(2)-3 = y
    y = 3

  • Algebra -

    Thank you
