Since TSQ and QSR are supplementary, they give 180 when summed. TSQ is 150, so QSR must be 30.
Therefore, you have

 
        
             
        
        
        
10% of 140 is 14 so just add 14 to 140
140+14=154.

Here is the equation:

Since both decimals are negative, the answer will be positive.
- Negative times Negative = Positive
 Divide both sides by -3.9 to leave the variable alone:

r is equal to 4 → r = 4
