Question

432÷(39-y÷12) =18 как решить?

Answer 1

Ответ:

180

Пошаговое объяснение:

432÷(39-1/12у)=18

432÷468-у/12=18

432×12/468-у=18

5184/468-у=18

5184=18(468-у)

288=468-у

у=468-288

у=180

Answer 2

Solving the equation:

432÷(39-y÷12)+=18

To solve this equation, we need to carefully follow the order of operations. First, we should evaluate what is inside the parentheses: (39-y÷12). According to the order of operations, division is performed before subtraction, so we divide y by 12. Next, we subtract the result of y÷12 from 39. Then, we divide 432 by the value inside the parentheses. Finally, we set the whole expression equal to 18 and solve for y.

Let's break this down step-by-step: 1. y÷12 = z (where z is the result of dividing y by 12) 2. 39 - z = a (where a is the result of subtracting z from 39) 3. 432÷a = b (where b is the result of dividing 432 by a) 4. b = 18 5. Solve for y

To solve for y, we would need to isolate it by reversing the operations. However, without being given a specific value for y, I cannot provide the final numerical solution. The key steps are carefully following the order of operations and isolating y through reversing the operations on both sides of the equation.
