Question

Х - 0,9х = 84;0,07х - 0,02х = 0,2;Помогите решить пожалуйста срочно.

Answer 1

0,07x-0,02x=0,2; 0,05x=0,2; x=0,2/0,05=4. x-0,9x=84; 0,1x=84; x=840

Answer 2

Solving the Equations

To solve the given equations, we can use the provided information and the standard methods of solving linear equations.

The given equations are: 1. Equation 1: \(x - 0.9x = 84\) 2. Equation 2: \(0.07x - 0.02x = 0.2\)

Solution

1. Equation 1: - Simplifying the equation, we get: \(0.1x = 84\) - Solving for \(x\), we have: \(x = \frac{84}{0.1}\) - Calculating the value of \(x\), we find: \(x = 840\)

2. Equation 2: - Simplifying the equation, we get: \(0.05x = 0.2\) - Solving for \(x\), we have: \(x = \frac{0.2}{0.05}\) - Calculating the value of \(x\), we find: \(x = 4\)

Therefore, the solution to the given equations is: - \(x = 840\) for Equation 1 - \(x = 4\) for Equation 2

I hope this helps! If you have any further questions, feel free to ask.
