Here's how to find what ' v ' must be :
-- Subtract 7 from each side .
-- Divide each side by 2 .
When you do that, you'll have v = (the number that ' v ' is) .
2v+7=3 Subtract 7 from both sides. 2v=-4 Divide both sides by 2. v=-2
The solution to the equation 2 v + 7 = 3 is v = − 2 . First, we subtract 7 from both sides, and then we divide by 2. This gives us the answer of − 2 .

Albert Einstein was born near the end of the 1800s in Ulm, Germany. He graduated from the University of Zurich in Switzerland at age 26. That was also when he did his famous work in physics. Fourteen years later, he won the Nobel Prize for Physics. For the next ten years, he lived in Germany and traveled a lot to talk to other scientists. Then, in the early 1930s, he had to leave Germany because of Hitler and the Nazi Party. He moved to the United States. From that time until his death, he lived in Princeton, New Jersey, where he continued his scientific work.
