Question

Как это решить срочно 0.15(х-4)+9.9-0.3(х-1)

Answer 1

Вроде так:
0.15(х-4)=9.9-0.3(х-1)
0,15х-0,6=9,9-0,3х+0,3
0,45х=10,8
х=24

Answer 2

Solving the Equation 0.15(x-4) + 9.9 - 0.3(x-1)

To solve the equation 0.15(x-4) + 9.9 - 0.3(x-1), we can follow a few steps to simplify and isolate the variable x.

1. Distribute the terms inside the parentheses: - 0.15(x-4) = 0.15x - 0.6 - 0.3(x-1) = 0.3x - 0.3

2. Combine like terms: - 0.15x - 0.6 + 9.9 - 0.3x + 0.3

3. Combine the x terms: - 0.15x - 0.3x

4. Combine the constant terms: - -0.6 + 9.9 + 0.3

5. Simplify the equation: - 0.15x - 0.3x = -0.6 + 9.9 + 0.3

6. Combine the x terms and the constant terms: - -0.15x = 9.6

7. Isolate the variable x: - Divide both sides by -0.15 to solve for x: - x = 9.6 / -0.15

Let's calculate the value of x using the equation x = 9.6 / -0.15.

Calculating the Value of x

By performing the division, we get:

x = 9.6 / -0.15 x = -64

So, the solution to the equation 0.15(x-4) + 9.9 - 0.3(x-1) is x = -64.
