Answer 1

Ответ:

15,3-2(x-0,9)=-0,7+3(x-2,4)​

15.3-2х+1.8=-0.7+3х-7.2

-2х-3х=-7.9-15.3-1.8

-5х=-25

х=-25/(-5)

х=5

Answer 2

Ответ:

х=5

Пошаговое объяснение:

15,3-2(x-0,9)=-0,7+3(x-2,4)

15,3-2х+1,8=-0,7+3х-7,2

17,1-2х=-7,9+3х

-2х-3х=7,9-17,1

-5х=-25

х=5

Answer 3

To solve the equation 15.3 - 2(x - 0.9) = -0.7 + 3(x - 2.4), you can follow these steps:

1. First, distribute the constants and simplify the equation:

15.3 - 2x + 1.8 = -0.7 + 3x - 7.2

2. Now, combine like terms by moving all the x terms to one side of the equation and the constants to the other side:

-2x - 3x = -0.7 - 7.2 - 15.3 + 1.8

3. Combine and simplify the constants on the right side:

-5x = -21.4

4. To isolate x, divide both sides by -5:

x = -21.4 / -5

5. Finally, simplify the fraction:

x = 21.4 / 5

x = 4.28

So, the solution to the equation is x = 4.28.
