8(8v-7)=12-4v
multiply the bracket by 8
(8)(8v)=64v
(8)(-7)=-56
64v-56=12-4v
move -4v to the other side
sign changes from -4v to +4v
64v+4v-56=12+4v
68v-56=12+4v-4v
68v-56=12
move -56 to the other side
sign changes from -56 to +56
68v-56+56=12+56
68v=12+56
68v=68
divide both sides by 68 to get v by itself
68v/68=68/68
cross out 68 and 68, divide by 68
then becomes 1*1*v=v
v=68/68
Divide the fraction by 68
68/68=1, 68/68=1
1*1=1
Answer:
v=1
