Answer:

1= X

Explanation:

Start with PEMDAS

3 x 4 is 12

3x -X is -3X

-3 x 2 is -6

-3 x -X is 3 X NEGITIVE X NEGATIVE = +

so now you got

12 - -3X -6 +3X

again - × - = +

so know you got 12 + 3X -6 +3X

Additions is next in PEMDAS

so 12 -6 is 6 and 3X + 3X is 6X

so 6X =6 so Divide by 6 and you get 1 =X
