Question

(x-2)*3,4-2,8(x+2)=4,4

Answer 1

Ответ:

(x-2)*3,4-2,8(x+2)=4,4

3,4-6,8-2,8x-5,6=4,4

0,6x-12,4=4,4

0,6x=4,4+12,4

0,6x=16,8

x=28

Answer 2

To solve the equation, let's first expand the expression:

(3.4 - 2.8)(x + 2) = 4.4

Now, perform the multiplication:

(0.6)(x + 2) = 4.4

Next, distribute the 0.6 to both terms inside the parentheses:

0.6x + 0.6 * 2 = 4.4

Simplify:

0.6x + 1.2 = 4.4

Now, isolate the variable x by subtracting 1.2 from both sides:

0.6x = 4.4 - 1.2

0.6x = 3.2

Finally, divide both sides by 0.6 to solve for x:

x = 3.2 / 0.6

x = 5.33 (rounded to two decimal places)

So the solution for the equation is x = 5.33.
