Answer:
-4(-7/30)-3/5=1/3  
 4(-1/15)+3/5=1/3
Step-by-step explanation:
1. -4x-3/5=1/3
-4x=1/3+3/5
-4x=14/15 <- divide both sides
x= -7/30
2. 4x+3/5=1/3
4x=1/3-3/5
4x= -4/15 <-divide both sides
x= -1/15
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
Equation
3x + 9 + 2x = x - 2x - 3               
Solution
Combine all the like terms.
3x+2x+9 =  x - 2x - 3
5x + 9 = -x - 3                            Add x to both sides of the equation
5x+x +9 = -x+x -3                      Combine
6x + 9 = - 3                                Subtract 9 from both sides of the equation
6x+9-9 = - 3-9                           Combine
6x = -12                                      Divide both sides by 6
6x/6 = -12/6
x = - 2
Answer x = - 2

Angle on a straight line sums up to 180 
so 
72+x + x+130 = 180 
2x = 180-72-130 
2x =-22
x= -11 
so Angle on the LHS is 61°
while angle on the RHS is 119°
