2x = -11 + 9
2x = -2 
x= 2/2
x= 1
        
                    
             
        
        
        
Answer:
-5
Step-by-step explanation:
First, distribute the 2 to the 3, -9, and 5. You will get 6 + 6 - 18 + 10 + (-9). Then, you can start from the beginning and work through combining the terms. The original equation is in bold after every step. 
6 + 6 - 18 + 10 + (-9)
6+6 = 12
12 - 18 + 10 + (-9)
12-18 = -6
- 6 + 10 + (-9)
-6 + 10 = 4 
4 + (-9) 
4 - 9 = -5

Watch closely.    I'll try to go slow.
Stop me if I go too fast, or if I do anything that you don't understand.
Ready ?
You said                               d      =  r t
Divide each side by ' t ' :    d / t  =  r
