Given equation is:

4x+12=8

Solving it, we get,

4x=-4 This is subtraction part. We are grouping the like terms on one side. So, 4x remains on one side and 8-12 will go to the other side.

x=(-4)/(4) This step includes division, to find the value of x

x=1

So, the correct answer is option A. Division
