B cause it's true if you look at the graph
        
             
        
        
        
Group and factor
group y's with y's and z's with z's
(y²-10y)+(10z-yz)
factor
y(y-10)+z(10-y)
force undistribute -1
-y(10-y)+z(10-y)
factor
(10-y)(-y+z)
(z-y)(10-y) or
(y-z)(y-10)
        
                    
             
        
        
        
So to get the answer you do 100100100+303030-101010 which = 100302120 x 10 (the amount she/he gets for each subscriber) which is the amount of money Kiersten earned.

2x + 4 = 3x - 10
-2x and +10 to both sides
14 = x
the answer is x = 14
