If we now that 4y equals to x, that means we can replace x with 4y.
Therefore we can write: 4y+2y = 12
We can summarize that to 6y = 12.
If we divide both sides with 6, you get y = 2
In order to solve for x, we can use the second equation and just replace y with value we just got (y=2).
We can write: x+2*2=12
Now you move 2*2 (which is 4) to the other side: x=12-4
Now you get: x = 8
The given scales which measure the attitude of a person is an ordinal scale such as a Likert scale
<h3>What is an ordinal scale?</h3>
An ordinal scale provides a report of the rating, order or rank of a data without stating the extent of variation between the categories.
There are many types of rating scales used to directly measure the attitude of a person towards a subject matter.
The Likert scale which is the most widely used rating scale, when applied, consists of a five or seven point scale, that empowers the subject of the survey to express how much they agree (or disagree) with a specified statement.
Generally, five options, graded from, mild to extreme are provided so that the survey subject can indicate (express), their strength of how much they agree with or feel about the statement or question
The assumptions of the Likert scale includes;
- The ability to measure attitudes.
- The intensity or strength of an attitude is linear, such that the attitude varies linearly from strongly agree to strongly disagree
Based on the perception of the subject, Likert scale can be used to also measure the variations of the following subject matters;
- Likelihood of an event or occurrence
- The importance of a product or service
- The quality perception of an object
- The frequency of an event

Answer: Around two gallon cans
Step-by-step explanation: One gallon can of paint covers up to 400 square feet, which is enough to cover a small room, like a bathroom. Two gallon cans of paint cover up to 800 square feet, which is enough to cover an average size room.
here, 7 cellphone,9 Tv, 12airconditioners = 8723
5 cellphone,7 Tv, 12airconditioners = 6523
or, 7,9,12=8723
-5,7,9=6523
______________
2,2,3=2191
then,
to make 4 cellphone , 4 tv set , 6 air conditioners add twice the answer ,
2,2,3=2191
+2,2,3=2191
____________
4,4,6=4382
hence,
the price of 4 cellphone , 4 tv set and 6 air conditioners is 4382 #
