Answer 2

Ответ:

5•(0,3х+6)-4•(0,2х-7)=-5

1,5х+30-0,8х+28=-5

0,7х+58=-5

0,7х= -5-58

0,7х= -63

х= -90

Answer 3

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

1. Distribute the constants to the terms inside the parentheses:

   1.5x + 30 - 0.8x + 28 = -5

2. Combine like terms:

   (1.5x - 0.8x) + (30 + 28) = -5

3. Simplify the equation:

   0.7x + 58 = -5

4. Now, subtract 58 from both sides to isolate the variable x:

   0.7x + 58 - 58 = -5 - 58

   0.7x = -63

5. Finally, divide both sides by 0.7 to solve for x:

   (0.7x) / 0.7 = (-63) / 0.7

   x = -90

So, the solution to the equation is x = -90.
