Answer:

V=-5

Step-by-step explanation:

first, subtract 9v from 3v. this will give you -6v=30. then divide by -6. you'll obtain v=(-5) as negitive divided/multiplied with a negative is positive, while positive  divided/multiplied by negative is always negative. To check, replace all v with -5, so it becomes (3-5)-(9-5)=30, and that equals -15-(-45)=30, and a negatives negative is positive so it becomes -15+45=30 which can be simplified to 45-15=30, and add 15 to both sides to obtain 45=45.
