Question

2,3*8-5(х:2-13)=10,4

Answer 1

2,3×8-5(х÷2-13)=10,4
13,4 (х÷2-13)=10,4
х÷2-13=13,4÷10,4
х÷2-13=0,77
х÷2=0,77+13
х÷2=13,77
х=13,77×2
х=27,54
Ответ: х=27,54
надеюсь будет правильно!

Answer 2

Let's solve the equation step by step:

2 * 3 * 8 - 5(x / 2 - 13) = 10.4

First, simplify the expression inside the parentheses:

x / 2 - 13

Next, distribute the -5 to both terms inside the parentheses:

-5 * (x / 2) + 5 * 13

Now, we have:

2 * 3 * 8 - 5 * (x / 2) + 5 * 13 = 10.4

Now, simplify further:

48 - 5 * (x / 2) + 65 = 10.4

Combine like terms:

113 - 5 * (x / 2) = 10.4

Now, isolate the term with x/2:

-5 * (x / 2) = 10.4 - 113

-5 * (x / 2) = -102.6

Now, divide both sides by -5 to solve for x:

(x / 2) = -102.6 / -5

(x / 2) = 20.52

Now, multiply both sides by 2 to solve for x:

x = 2 * 20.52

x = 41.04

So, the solution for the equation is x = 41.04.
