Let x be the pens and y be the pencils
Given:
Brian purchased pens for 75 cents each and pencils for 40 cents each he bought total of 22 writing utensils for $11.95.
Total pens and pencils is 22
So,  ----------------(1)
----------------(1)
And he bought all utensils for $11.95. and each pen for 75 cents and pencils for 40 cents.
 ------------(2)
------------(2)
solve equation 1 and equation 2 for x and y.
From equation 1.

 ----------------(3)
----------------(3)
put y value in equation 2.







Now substitute x value in equation 3.


So, he buy 13 pencils.

-3, 1 is the answer because the spot is on the -3 and in the first low with the Y-axis and stuff .
        
                    
             
        
        
        
7x+6=3x-6
    +6       +6
7x+12=3x
-3x       -3x
 4x+12=0
-4x         -4x
 divide both sides by -4 but you have to flip the sign.   
-3>x
or  
{x | x < -3}
