Question

7 x + 9 x +3,2 = 27, 2​

Answer 1

Ответ:

х = 1,5

Пошаговое объяснение:

7х + 9х = 27,2 - 3,2

16х =24

х = 24:16

х = 1,5

Answer 2

Переносим все числа вправо с противоположным знаком:

7х + 9х = 27,2 - 3,2

Приводим подобные:

16х =24

Избавляемся от коэффициента перед переменной (в таком случае мы число справа делим на коэффициент):

х = 24:16

х = 1,5

Answer 3

It seems like you have an equation with some mathematical expressions. Let's solve it step by step:

7x + 9x + 3.2 = 27.2

First, combine the like terms on the left side of the equation:

(7x + 9x) + 3.2 = 27.2

Now, add the coefficients of x:

16x + 3.2 = 27.2

Next, subtract 3.2 from both sides of the equation to isolate the variable:

16x = 27.2 - 3.2 16x = 24

Now, divide both sides by 16 to solve for x:

x = 24 / 16 x = 1.5

So, the solution to the equation is x = 1.5.
