Julie subscribe to a sports magazine and a fashion magazine. she received 24 issues this year. the number of fashion issues is 6 less than twice the number number of sport issues. define the variable, and write a system of equations to find the number of each magazine.
how would i set this up?

Let s be the number of sports issues, and let f be the number of fashion issues, then

s + f = 24    (this represents the total number of magazines)

and

f = 2s - 6      (number of fashion issues is 6 less that twice the number of

                      sports issues)

Step-by-step explanation:

You want to assign a variable for each piece of the problem, here you need a variable for the number of sports magazines and one for the number of fashion magazines.  

Then you set up a system of equations based on the given information.  

There are 24 total magazines, so the number of sports magazines, and the number of fashions magazines adds up to 24, or

sports  + fashion = 24

The number of fashion magazines is 6 less than twice as many sports magazines, so

f = 2s - 6              

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
