(2x+4)=-4(-2x-6)
distribute -4 to (-2x-6) by multiplying
negative multiplied by a negative is a positive
8x+24=2x+4
subtract 24 from each side
8x=2x-20
subtract 2x from each side 6x=-20

-20/6
simply to -10/3 or -3 1/3 or -3.3
x=-10/3

The operation is known as rounding of a number.
This means basically if i measure the temperature of a city and it comes out to be 22.9 degrees. I will round it of to 30 degrees or the amount of significant figures i am designated with.
Similarly if its 22.85 and i have to round of to 3 significant figures it becomes 22.9 degrees.
ROunding off is obviously done watching to which digit we have to.
