The variable was whether people approve or disapprove of the president. They were trying to poll just the people that live in the main part of the USA. There is slight bias that comes from excluding Alaska and Hawaii.
Convert all fractions to have the same denominator.
To convert, we must find the least common multiple of the two denominators of the fractions:
Multiples of 4: {4,8,12,16,20}
Multiples of 5: {5,10,15,20}
The least common multiple of 4 and 5 is 20.
Multiply the fractions by a number that will result in the denominator being 20:


The equation should now look like this:

Subtract both sides by 8/20 to get w by itself:


The value of w is 7/20.
I would try a but maybe wait for one more response because I got squared after x and 5x
