Answer:
1 solution
Step-by-step explanation:
4x + x + 3 = 4x (Subtract 4x from both sides)
x + 3 = 0 (Subtract 3 from both sides)
x = -3
 
        
             
        
        
        
Even numbers are numbers that can be divisible by 2, so in this case
28, 30, 32, 34, 36, 38
^ are even numbers because they can be divided by 2
        
             
        
        
        
300/x=100/100
(300/x)*x=(100/100)*x       - we multiply both sides of the equation by x
300=1*x       - we divide both sides of the equation by (1) to get x
300/1=x 
300=x 
x=300
now we have: 
100% of 300=300
The answer is 300
