Answer:true!!!
Step-by-step explanation:
 
        
             
        
        
        
3x + 5y = 1 . . . . . . . . (1)
7x + 4y = -13 . . . . . . .(2)
(1) x 7: 21x + 35y = 7 . . (3)
(2) x 3: 21x + 12y = -39 .(4)
(3) - (4) = 23y = 46
y = 46/23 = 2
        
             
        
        
        
Answer:
the answer is 5 because 40 divided by 8 is 5
 
        
                    
             
        
        
        
If you only want to know what it means ¨c¨ then it is the Denominator, cause you are referring a fraction.
        
             
        
        
        
Well, there are two solutions.
Add both sides by 15.75 then from here, you can use quadratic formula.
So your answer should be x = -2.44949 or 2.44949.
