    20=7k+20+2

    Simplify:

    20=7k+20+2

    20 = (7k) + (20+2) (Combine Like Terms)

    20=7k+22

    Flip the equation.

    7k+22=20

    Subtract 22 from both sides.

    7k+22-22=20-22

    7k=-2

    Divide both sides by 7.

    7k/7=-2/7

    k=-2/7

    20 = 7k + 20 + 2

    20 = 7k + 22

    20 - 22 = 7k + 22 - 22

    -2 = 7k

    k = - 2/7
