Answer:
<h2>v = 0</h2><h2 />
Step-by-step explanation:
-7 + 4v = -7v -7(1 - 6v) 
⇔
-7 + 4v = -7v - 7 + 42v
⇔
4v = -7v + 42v
⇔
4v = 35v
⇔ 
35v - 4v = 0
⇔
31v = 0
⇔
v = 0
 
        
             
        
        
        
Answer:
6 3/4x
Step-by-step explanation:
If you follow PEMDAS (Parenthesis, Exponent, Multiply, Divide, Add, Subtract) then you do what is inside the parenthesis first.
3 1/2 divided by 2= 1 3/4
1 3/4 plus 5= 6 3/5
Then, you add the x and since there is no other variable like x, then you just leave it with 6 3/4.
Hope that helped! :)
