Answer:
V=6/13.5
Step-by-step explanation:
8-8.5(v)=6v+2-v
We move all terms to the left:
8-8.5(v)-(6v+2-v)=0
We add all the numbers together, and all the variables
-8.5v-(5v+2)+8=0
We get rid of parentheses
-8.5v-5v-2+8=0
We add all the numbers together, and all the variables
-13.5v+6=0
We move all terms containing v to the left, all other terms to the right
-13.5v=-6
v=-6/-13.5
v=6/13.5
