Question

5(0,3x+6)-5=-4(0,2x-7)​

Answer 1

Ответ:

5*0.3x+5*6=-4*0.2x-4*7

1.5x+30=-0.8x-28

1.5x+0.8x=-28-30

2.3x=-58

x=-58/2.3

x=-1 12/2.3

Answer 2

To solve the equation 5(0.3x + 6) - 5 = -4(0.2x - 7), follow these steps:

1. Distribute the constants on both sides of the equation:

   0.15x + 30 - 5 = -0.8x + 28

2. Combine like terms on each side of the equation:

   0.15x + 25 = -0.8x + 28

3. Move all the terms containing x to one side of the equation and the constants to the other side. You can do this by adding 0.8x to both sides and subtracting 25 from both sides:

   0.15x + 0.8x = 28 - 25

4. Combine the x-terms on the left side of the equation:

   0.95x = 3

5. Divide both sides by 0.95 to isolate x:

   x = 3 / 0.95

6. Simplify the right side:

   x ≈ 3.1579

So, the solution to the equation is approximately x ≈ 3.1579.
