Question

13+3,2x+0,4x=40(уравнение)​

Answer 1

Решение:

13+3,2х+0,4х=40

3,2х+0,4х=40-13

3,6х=27

х=27:3,6

х=7,5.

Answer 2

3,2x+0,4x=40-13

3,6x=27

x=27/3,6

x=7,5

Answer 3

To solve the equation, we need to find the value of 'x' that satisfies the equation. Here's the equation:

13 + 3.2x + 0.4x = 40

Let's combine the 'x' terms:

3.2x + 0.4x = 3.6x

Now, the equation becomes:

13 + 3.6x = 40

To isolate 'x,' we'll first subtract 13 from both sides:

3.6x = 40 - 13 3.6x = 27

Now, divide both sides by 3.6 to find the value of 'x':

x = 27 / 3.6 x = 7.5

So, the solution to the equation is x = 7.5.
