    7x+1 = (1/3)

    2x + 2y = 28

    Systems of equations.

    Solve equation with single variable first.

    7x+1 = (1/3), x = (-2/21)

    Substitute the value of x in second equation and solve for y.

    2 (-2/21) + 2y = 28, y = (296/21)

    I'm assuming that isn't the correct answer because you wrote the first equation incorrectly.
