Question

(0,5a +1,4b)-(-1,9b-0,1a)-(3,3b +0,6a) = 0.​

Answer 1

Ответ:

расскрываем скобки
0,5а+1,4b+1.9b+0.1a-3.3b-0.6a
теперь подобные слагаемые:
0.5a+0.1a-0.6a=0
1.4b+1.9b-3.3b=0

итог: у нас все буквы а получили ноль все бувы б получили ноль значит что:0+0=0

Answer 2

To solve the expression (0.5a + 1.4b) - (-1.9b - 0.1a) - (3.3b + 0.6a) = 0, you need to simplify it step by step:

1. Distribute the negative sign inside the second set of parentheses:

   (0.5a + 1.4b) + (1.9b + 0.1a) - (3.3b + 0.6a) = 0

2. Combine like terms by collecting the "a" terms and the "b" terms separately:

   (0.5a + 0.1a) + (1.4b + 1.9b) - (3.3b + 0.6a) = 0

3. Simplify each term:

   (0.6a) + (3.3b + 1.9b) - (3.3b + 0.6a) = 0

4. Now, combine like terms again:

   0.6a + 5.2b - 3.3b - 0.6a = 0

5. You can see that the "a" terms (0.6a and -0.6a) cancel out:

   5.2b - 3.3b = 0

6. Finally, subtract 3.3b from 5.2b:

   1.9b = 0

7. To solve for "b," divide both sides by 1.9:

   b = 0 / 1.9

   b = 0

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