2v + 18 = 16 - 4(v + 7)<br> please help, thank you
tia_tia [17]

Answer:

v=−5

Step-by-step explanation:

2v + 18 = 16 - 4(v + 7)

2v+18=16−4(v+7)

2v+18=16+(−4)(v)+(−4)(7)(Distribute)

2v+18=16+−4v+−28

2v+18=(−4v)+(16+−28)(Combine Like Terms)

2v+18=−4v+−12

2v+18=−4v−12

Add 4v to both sides.

2v+18+4v=−4v−12+4v

6v+18=−12

Subtract 18 from both sides.

6v+18−18=−12−18

6v=−30

Divide both sides by 6.

6v /6 = −30 /6

v=−5
