Answer:
3*(5*x-7)-(15*x-21)=0 
Step-by-step explanation:
3 • (5x - 7) -  (15x - 21)  = 0 
Step  2  :
Equation at the end of step  2  :
  0  = 0 
Step  3  :

Answer:
Step-by-step explanation:
plug y into the first equation:
8x+5y=24
8x+5(-4x)=24
8x-20x=24
-12x=24
x=-24/12
x=-2
then plug x to the second equation
y=-4
y=-4(-2)
y=8
x=-2
y=8
 
        
                    
             
        
        
        
Answer:
$11
Step-by-step explanation:
Kim has $20
