Ok so first, let's combine the like terms on the right side by adding them
Now we look at them put back together
Now you have to move all your y's to one side and numbers without a variable to the other. So, for this we're going to add 6y to 7y on the right so the left side cancels out.
On the other side we subtract 6 from 19
and now to get the answer for y we divide 13 by 13 to get your answer of 1 :)
The way to convert counts into relative frequencies in a Two Way Relative Frequency Table is to divide the count by the total number of items
<h3>What is a Frequency Table?</h3>
This refers to the depiction of the number of times in which an event occurs in the form of a table.
Hence, when a two-way frequency table is used, it shows the visual representation of the possible relationship between different sets of data.
Please note that your question is incomplete as you did not provide the frequency table needed and also the trends and generalizations to find, so a general overview was given.

First you had to add by seven from both sides of equation form.
Then simplify by equation.
Next, you multiply by two from both sides of equation form.
And finally, simplify by equation.
Final answer: 
Hope this helps!
And thank you for posting your question at here on brainly, and have a great day.
