X= -3
Solution:
 takeaway 4 from each side 
 x+3=0
 subtract 3 from each side 
 x=-3
        
                    
             
        
        
        
Answer:
first bring x value together
Step-by-step explanation:
like 2x and 3x together and then take 5/3 to RHS and solve 
 
        
                    
             
        
        
        
To solve, lets convert the number so that they both have the similar exponents.

in comparing 20,000*10^-28 and 9*10^-28, we can see that one is nearly 2,000 times bigger than the other
20,000/9=2222

Answer:
X=45
Step-by-step explanation:
You see the congruency markings use B.A.T to determine that the unmarked angle is x, therefore 4x=180 and x=45
 
        
             
        
        
        
Answer:
49 and 46
