Answer 1

Ответ:

x=63,4 как-то так получилось что ли

Answer 2

Let's solve the equation step by step.

-7,2 - 4,5(х + 3) = 1 - 5(х - 2)

First, distribute the -4,5 and -5 terms:

-7,2 - 4,5х - 13,5 = 1 - 5х + 10

Combine like terms on both sides:

-7,2 - 13,5 - 4,5х = 1 - 5х + 10

Simplify further:

-20,7 - 4,5х = 11 - 5х

Next, let's isolate the terms with x on one side of the equation. We can do this by adding 4,5х and 5х to both sides:

-20,7 - 4,5х + 4,5х + 5х = 11 - 5х + 4,5х + 5х

Simplify:

-20,7 + 0,5х = 11

Now, isolate the term with x by subtracting -20,7 from both sides:

-20,7 + 20,7 + 0,5х = 11 + 20,7

Simplify:

0,5х = 31,7

Finally, solve for x by dividing both sides by 0,5:

(0,5х) / 0,5 = 31,7 / 0,5

Simplify:

х = 63.4

Therefore, the solution to the equation is x = 63.4.
