Question

0,9*(х+4)-0,3*(2х-3)=0,6х+4,5

Answer 1

Ответ:

x = 0

Пошаговое объяснение:

0,9*(х+4)-0,3*(2х-3)=0,6х+4,5

0,9x + 3,6 - 0,6x + 0,9 = 0,6x + 4,5

0,9x - 0,6x - 0,6x  =  4,5 - 3,6 - 0,9

-0,3x = 0

x = 0

Answer 2

To solve the equation 0.9*(x+4) - 0.3*(2x-3) = 0.6x + 4.5, follow these steps:

1. Distribute the coefficients on both sides of the equation to eliminate the parentheses: 0.9x + 0.94 - 0.32x + 0.3*3 = 0.6x + 4.5

2. Perform the multiplications: 0.9x + 3.6 - 0.6x + 0.9 = 0.6x + 4.5

3. Combine like terms on both sides of the equation: (0.9x - 0.6x) + (3.6 + 0.9) = 0.6x + 4.5

4. Simplify the equation: 0.3x + 4.5 = 0.6x + 4.5

5. Now, you want to isolate the variable x. To do that, you can move the terms involving x to one side of the equation and the constants to the other side. Subtract 0.3x from both sides:

   0.3x - 0.3x + 4.5 = 0.6x - 0.3x + 4.5

6. This simplifies to: 4.5 = 0.3x

7. Finally, solve for x by dividing both sides by 0.3:

   x = 4.5 / 0.3 x = 15

So, the solution to the equation is x = 15.
