3x − 6y = –6 x = 2 solve using substitution.

y=2

Step-by-step explanation:

First, you substitute x with 2.

3(2)-6y=(-6)

Then, you multiply:

6-6y=(-6)

Next, you subtract 6 from -6. So, the first 6 gets crossed out because of inverse of operation.

-6y=-12

Finally, you divide -6 to both sides of the equation to get y=2

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
