Question

(x-135)÷45=x÷72пжжжжж​

Answer 1

Ответ:

360

Объяснение:

Запишем в виде дроби и применим основное свойство пропорции.

$\frac{x - 135}{45} = \frac{x}{72} \\ 72(x - 135) = 45x \\ 72x - 9720 = 45x \\ 72x - 45x = 9720 \\ 27x = 9720 \\ x = \frac{9720}{27} \\ x = 360$

Answer 2

To solve the equation "(x-135)÷45=x÷72", we can start by simplifying the expression on both sides of the equation.

Let's begin by expanding the divisions:

(x - 135) ÷ 45 = x ÷ 72

Now, we can multiply both sides of the equation by the common denominator of 45 and 72, which is 3240:

3240 * [(x - 135) ÷ 45] = 3240 * (x ÷ 72)

Simplifying further:

72(x - 135) = 45x

Expanding the multiplication:

72x - 9720 = 45x

To isolate the variable, let's move all the terms with x to one side of the equation:

72x - 45x = 9720

Simplifying:

27x = 9720

Now, we can solve for x by dividing both sides of the equation by 27:

x = 9720 ÷ 27

Calculating:

x = 360

Therefore, the solution to the equation "(x-135)÷45=x÷72" is x = 360.
