Answer: a=1.4
Step-by-step explanation:
move the 0.1a to the other and the 7 to the other side which will make the  7 positive and the 0.1a negative.
5a-0.1= 4.9a
-0.14+7=6.86
dive both sides by 4.9 and you get 
a=1.4
 
        
             
        
        
        
You put 6 on one side then equal it to 9 with at variable of "X" with it multiplied by 3 to make the thing an equation
