Question

-0,7 (х+3)+3=3-0,3(х-1)​

Answer 1

Ответ:

х= -6

Пошаговое объяснение:

= -0,7х-2,1=-0,3х+0,3=

=-0,7х+0,3х=0,3+2,1=

=-0,4х=2,4=

= х= -6

Answer 2

To solve the equation -0.7(x + 3) + 3 = 3 - 0.3(x - 1), you can follow these steps:

1. Distribute the constants on both sides of the equation: -0.7x - 2.1 + 3 = 3 - 0.3x + 0.3

2. Combine like terms on each side of the equation: -0.7x + 0.9 = 3 - 0.3x + 0.3

3. Move all terms involving x to one side of the equation and constants to the other side. To do this, you can add 0.3x to both sides and subtract 0.9 from both sides: -0.7x + 0.3x = 3 + 0.3 - 0.9

4. Combine like terms on both sides: -0.4x = 3.3 - 0.9

5. Subtract 0.9 from 3.3 to simplify the constants on the right side: -0.4x = 2.4

6. Now, divide both sides by -0.4 to solve for x: x = 2.4 / (-0.4)

7. Simplify the division: x = -6

So, the solution to the equation is x = -6.
