Answer:
the answer is 9
Explanation:
why it 9 Add '2.7' to each side of the equation. 
-2.7 + 2.7 + 0.3x = 9 + 2.7 
 
Combine like terms: -2.7 + 2.7 = 0.0 
0.0 + 0.3x = 9 + 2.7 
0.3x = 9 + 2.7 
 
Combine like terms: 9 + 2.7 = 11.7 
0.3x = 11.7 
 
Divide each side by '0.3'. 
x = 39 
 
Simplifying 
x = 39
