5(v-3)-7v=1

mutiply the bracket by 5

(5)(v)(5)(-3)-7v= 1

5v-15-7v

5v-7v-15 - combing like terms

5v-7v-15= 1

-2v-15= 1

move -15 to the other side

sign changes from -15 to +15

-2v-15+15= 1+15

-2v=16

divide by -2 for both sides

-2v/-2= 16/-2

Cross out -2 and -2, divide by -2 then becomes 1*1*v= v

v= -8

Answer: v=-8
