Answer:

You subtract 9 from both sides

Step-by-step explanation:

You have to get the variable by itself to solve so you subract 9 by 9 and they cancel each other out. Then you do -12-9 and since they are both negative you get get -21

Them you have your answer m=-21, you can check this by plugging m inot the equation

if you’re good with set theory and this sudoko puzzle in math 30 please help with question 33!! real answers only !!
Sidana [21]

Answer:  A) 2, 7, 9

<u>Step-by-step explanation:</u>

In a sudoku puzzle, there are three rules:

  1. Each vertical line must contain the numbers 1 - 9, with no duplicates
  2. Each horizontal line must contain the numbers 1 - 9, with no duplicates
  3. Each 3 x 3 box must contain the numbers 1 - 9, with no duplicates.

Using logic:

2 must go in the 1st box. It cannot go in the 2nd or 3rd shaded square because 2 is already in that 3 x 3 box.

That leaves the 2nd and 3rd shaded square.  

9 cannot go in the 2nd shaded square because 9 is already in that vertical line.

Therefore, 9 must go in the 3rd shaded square.

That leaves the 2nd shaded square.

7 must go in the 2nd shaded square because it is the only number remaining (2 and 9 have already been placed in the other squares).
