Question

(7,2x + 5)-12,35 = 30,81​

Answer 1

7,2x+5-12,35=30,81
7,2x-7,35=30,81
7,2x=30,81+7,35
7,2x=38,16
x=5,3
Ответ: 5,3

Answer 2

It seems like you have provided an equation. Let's solve it step by step:

(7 * 2x + 5) - 12.35 = 30.81

First, distribute the 7 to the 2x and the 5 inside the parentheses:

14x + 5 - 12.35 = 30.81

Now, subtract 12.35 from both sides of the equation:

14x - 7.35 = 30.81

Next, isolate the term with the variable (14x) by adding 7.35 to both sides:

14x = 38.16

Finally, solve for x by dividing both sides by 14:

x = 38.16 / 14 x = 2.725714285714286

So, the solution for the equation is approximately x = 2.7257.
