Answer:
12v-38=1/8
We move all terms to the left:
12v-38-(1/8)=0
We add all the numbers together, and all the variables
12v-38-(+1/8)=0
We get rid of parentheses
12v-38-1/8=0
We multiply all the terms by the denominator
12v*8-1-38*8=0
We add all the numbers together, and all the variables
12v*8-305=0
Wy multiply elements
96v-305=0
We move all terms containing v to the left, all other terms to the right
96v=305
v=305/96
v=3+17/96
(Hope that helps)
