Question

4n+2=6n+7 решите уравнение

Answer 1

4n+2=6n+7

4n-6n=7-2

-2n= 5

n = 5 : (-2)

n = -5/2

n = - 5/2

_______________

- 2 * ( - 5/2 ) = 5

5 = 5

Answer 2

4n+2=6n+7

4n-6n=7-2

-2n=5

n=5:(-2)

n=-2,5

Answer 3

To solve the equation 4n + 2 = 6n + 7, we need to isolate the variable n on one side of the equation. Here's the step-by-step solution:

1. Start by moving the constant terms to one side and the variable terms to the other side of the equation.

   Subtract 4n from both sides: 4n + 2 - 4n = 6n + 7 - 4n

   Simplify: 2 = 2n + 7

2. Next, move the constant term (7) to the other side of the equation by subtracting 7 from both sides:

   2 - 7 = 2n + 7 - 7

   Simplify: -5 = 2n

3. Finally, solve for n by dividing both sides by 2:

   n = -5 / 2

   n = -2.5

So, the solution to the equation is n = -2.5.
