Solve for y:

-y+6+6y=9

-y + 6 + 6y = 9

First, simplify -y + 6 + 6y to 5y + 6. / Your problem should look like: 
Second, subtract 6 from both sides. / Your problem should look like: 
Third, subtract 9 - 6 to get 3. / Your problem should look like: 
Fourth, divide both sides by 5. / Your problem should look like: 

Answer as fraction: y = 
Answer as decimal: 0.6

−y+6+6y=9

(−y+6y)+(6)=9(Combine Like Terms)

5y+6=9

Subtract 6 from both sides.

5y+6−6=9−6

5y=3

Divide both sides by 5.

5y/5=3/5

y=3/5

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
