Answer:

Step-by-step explanation:

- 13 = 7+5v

subtract 7 on both sides to cancel out 7

- 20 = 5v

divide both sides by 5 to isolate v

- 4 = v, v is negative because negative divided by a positive will make your answer stay negative

   


ANSWER: V=4

EXPLANATION: First you would subtract 7 from both sides, then that should leave you with -20=5v divide five from both side you get the answer V=4.
