    x = 1

    Step-by-step explanation:

    Step 1: Choose one of the equations to solve for y:

    x - y + 1 = 0

    (-y) / - 1 = (-1 - x) / - 1

    y = 1 + x

    Step 2: Plug in y into either equation

    3x + 2 (1 + x) = 7

    3x + 2 + 2x - 2 = 7 - 2

    5x / 5 = 5 / 5

    x = 1

    Answer: x = 1
