Answer:
x=-5, y=-2
Step-by-step explanation:
3x+2y= -19  
-3x-5y= 25
Add the two equations together
3x+2y= -19  
-3x-5y= 25
------------------
0x -3y = 6
Divide each side by -3
-3y/-3 = 6/-3
y = -2
Now find x
3x+2y = -19
3x +2(-2) =-19
3x-4 = -19
Add 4 to each side
3x -4+4 = -19+4
3x= -15
divide by 3
3x/3 = -15/3
x = -5
 
        
                    
             
        
        
        
E^3t=100
ln100=3t
t=(ln100)/3
        
             
        
        
        
To find three equivalent fractions of a fraction, simply multiply the fraction by a common factor.
For example, multiple both the numerator and denominator of 9/7 by 2.
This will give you a fraction of 18/14, which is equivalent.
You can do this with any number you like to create three equivalent fractions.
