Решить уравнение -2n=5.6n

Answer 1

-2n-5.6n=0

n=0

........................

Answer 2

$-2n=5,6n \\ -2n-5,6n=0 \\ -7,6n=0 \\ n=0$

Answer 3

To solve the equation -2n = 5.6n, you want to isolate the variable n on one side of the equation. Here's the step-by-step solution:

Step 1: Combine the n terms on one side of the equation by moving 5.6n to the left side.

Add 5.6n to both sides of the equation: -2n + 5.6n = 5.6n + 5.6n (5.6n - 2n) = 5.6n + 0

Step 2: Simplify the equation:

3.6n = 5.6n

Step 3: Now, move all the n terms to one side of the equation. We can do this by subtracting 3.6n from both sides:

3.6n - 3.6n = 5.6n - 3.6n 0 = 2n

Step 4: Divide both sides by 2 to solve for n:

0/2 = 2n/2 0 = n

So, the solution to the equation is n = 0.
