    Step 1: Solve 3x - 5y = - 1 for x

    Add 5y to both sides

    Divide both sides by 3

    Substitute 5/3y + - 1/3, for x.

    Simplify both sides of the equation

    Add 2/3 to both sides

    Divide both sides by 3 and 1/3

    Y=2

    Substitute 2 for y in x = 5/3y + - 1/3

    Simplify both sides of the equation

    X=3
