Question

0,3n - (2,6 - 0,9n) = 1,2n + 3

Answer 1

Ответ:

0,3n-2,6+0,9=1,2n+3

0,3n-1,2n=3-0,9+2,6

-0,9n=4,7

n= - 5,22 или 5(целых) 22/100(дробь)

Answer 2

To solve the equation, we need to find the value of 'n' that makes both sides of the equation equal. Let's simplify the equation step by step:

0. First, let's remove the parentheses:

0,3n - (2,6 - 0,9n) = 1,2n + 3

0.3n - 2.6 + 0.9n = 1.2n + 3

1. Combine like terms on both sides of the equation:

0.3n + 0.9n - 1.2n = 3 + 2.6

0.3n - 0.3n = 5.6

2. The 'n' terms cancel out:

0 = 5.6

3. Since the equation simplifies to "0 = 5.6", there is no value of 'n' that can satisfy this equation. Therefore, there is no solution to this equation.
