Answer 1

Ответ:

Пошаговое объяснение:

7(6у-5)-0,4(у-3)= -1,16

42у-35-0,4у+1,2= -1,16

42у-0,4у= -1,16+35-1,2

41,6у=32,64

у=32,64:41,6

у=32 16/25 : 41 3/5

у=816/25:208/5

у=816/25*5/208

у=51/65

Answer 3

To solve the equation 7(6у-5) - 0.4(у-3) = -1.16, you can follow these steps:

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

   42у - 35 - 0.4у + 1.2 = -1.16

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

   (42у - 0.4у) - (35 - 1.2) = -1.16

3. Simplify further:

   41.6у - 33.8 = -1.16

4. Add 33.8 to both sides to isolate the variable:

   41.6у = -1.16 + 33.8

5. Calculate the right side:

   41.6у = 32.64

6. Divide both sides by 41.6 to solve for у:

   у = 32.64 / 41.6 у ≈ 0.7846

So, the solution to the equation is у ≈ 0.7846.
