12x -7 = 29

12x - 7 + 7=29 +7

12x + 0 = 36

12x = 36

12x/12 = 36 /12

1x=3

x=3

12x -7 = 29

12x - 7 + 7=29 +7

12x + 0 = 36

12x = 36

12x/12 = 36 /12

1x=3

x=3

Hi again Travina;

Let's add 7 to both sides...

Let's add the numbers together...

12x+0=36

We do not need the zero...

Let's divide both sides by 12...

Let's note that 12/12=1

Let's note that 36/12=3

Let's note that 1x=x

No further attention is required.
