Answer:
x = 8.45
Step-by-step explanation:
5.4 + 0.2x = 7.09
Subtract 5.4 from both sides to leave 0.2x alone
0.2x = 1.69
Divide by 0.2 on both sides to isolate x
x = 1.69/0.2
x = 8.45
 
        
             
        
        
        

We effectively rewrite the equation as

In order for the LHS to be defined, we need to restrict  , or
, or  . Now, the LHS will vanish when the numerator is 0, which happens for
. Now, the LHS will vanish when the numerator is 0, which happens for

This value is indeed smaller than 4, so the solution is  .
