20=8+v i dont know how to do this

Answers

20 = 8 + v equals v = 12.

First, subtract 8 from both sides. Your problem should look like: 20 - 8 = v
Second, simplify 20 - 8 to get 12. Your problem should look like: 12 = v.
Third, switch sides to get v = 12, which is the correct answer.

You subtract 8 from both sides so the answer is v=12

(3x - 15) / 2 = 4x
3x - 15 = 8x
-15 = 5x
x=-3

Final answer:

To solve the equation (3x - 15) / 2 = 4x, we start by multiplying both sides by 2. Then, we subtract 3x from both sides. Finally, we divide both sides by 5 to find that x = -3.

Explanation:

Your question is to solve the equation (3x - 15) / 2 = 4x. We can start solving this equation by following steps:

First, multiply both sides of the equation by 2 to get rid of the denominator. This will give us the equation: 3x - 15 = 8x.
Second, subtract 3x from both sides to gather the x terms on one side of the equation. This will result in: -15 = 8x - 3x, which simplifies to -15 = 5x.
Finally, divide both sides of the equation by 5. This will yield the solution: x = -15 / 5, which simplifies to x = -3.

So, the solution to the equation is x = -3.
