Question

Х/у - дробьх-(х*4/15+х*2/5)=90нужно решение! Не только ответ

Answer 1

x-(4/15x(дополнительный множитель 1)+2/5x(дополнительный множитель 3))=90

умножаем на дополнительные множители и получаем

x-(4+6/15x)=90,

x-10/15x=90,

представляем x как15/15x и получаем

15/15x-10/15x=90 получаем 5/15x=90 сокращаем и получаем

1/3x=90

x=90/ 1/3

x=270

Answer 2

Solving the Equation

To solve the equation х/у - х*(4/15 + х*2/5) = 90, we can follow these steps:

1. First, simplify the expression inside the parentheses. 2. Then, solve for the variable х.

Let's proceed with the solution.

Step 1: Simplify the Expression

The given equation is х/у - х*(4/15 + х*2/5) = 90.

Simplify the expression inside the parentheses: 4/15 + 2x/5 = (4 + 6x)/15

So, the equation becomes: х/у - х*(4 + 6x)/15 = 90

Step 2: Solve for the Variable х

To solve for х, we need to isolate it on one side of the equation. Let's proceed with the calculation.

х/у - х*(4 + 6x)/15 = 90

Multiply through by 15у to clear the fraction: 15х - ху(4 + 6x) = 90у

Now, we can solve for х.

Conclusion

The solution to the equation х/у - х*(4/15 + х*2/5) = 90 involves simplifying the expression and then solving for the variable х. If you need further assistance with the specific values of х and у, please provide them for a more detailed solution.
