Answer:
There were 261 Cheeseburgers and 87 Hamburgers sold on Tuesday
Step-by-step explanation:
Lets write some equations where H=Hamburgers and C=Cheeseburgers:
1) H+C=348
2) C=3H
1) Substitute 3H as C in the first equation:
3H+H=348
2) Combine alike terms:
4H=348
3) Divide both sides by 4:
H=87
4) Now, substitute 87 as H in the first equation:
87+C=348
5) Subtract 87 from both sides:
C=261
 
        
             
        
        
        
Answer:
x=20
Step-by-step explanation:
x=20 because 4×20=80 
and 80-20= 60
 
        
                    
             
        
        
        
x=0
let's solve your equation step-by-step
2(4x+3)-12=3x-6
(8x)+(6-12)=3x-6
8x-6=3x-6
subtract 3x from both sides.
8x-6-3x=3x-6-3x
5x-6+6=-6+6
5x=0
5x/5=0/5
x=0 
I hope that helps you
