The answer to your question is below

Step-by-step explanation:

In Mayan notation there are only 3 symbols

   dot   .    means one

   line   ---   means five

  snail          means zero

And the are three levels,     the lower means     x 1

                                              the first means       x 20

                                              the second means  x 400

                                              the higher means    x 8000

Then, 135 is lower than 400, so we must start in the first level and need to divide 135 by 20.                         6

                                        20    135

                                                   15

Finally place 6 in the fist level and 15 in the lower lever, like this

And 120 + 15 = 135.          

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
