\left(v-7\right)\times 8=\left(v-1\right)\left(-4\right)
Variable v cannot be equal to any of the values 1,7 since division by zero is not defined. Multiply both sides of the equation by \left(v-7\right)\left(v-1\right), the least common multiple of v-1,v-7.
8v-56=\left(v-1\right)\left(-4\right)
Use the distributive property to multiply v-7 by 8.
8v-56=-4v+4
Use the distributive property to multiply v-1 by -4.
8v-56+4v=4
Add 4v to both sides.
12v-56=4
Combine 8v and 4v to get 12v.
12v=4+56
Add 56 to both sides.
12v=60
Add 4 and 56 to get 60.
v=\frac{60}{12}
Divide both sides by 12.
v=5
Divide 60 by 12 to get 5.
