Пошаговое объяснение:

х = 59

Answer 3

To solve the equation (-5,7 - 12,8) + x = 40,5, you need to isolate the variable x.

Start by adding 5,7 and 12,8 to both sides of the equation to isolate x:

(-5,7 - 12,8) + x + 5,7 + 12,8 = 40,5 + 5,7 + 12,8

Now, simplify the equation:

x - 17,5 = 58

Next, to isolate x, add 17,5 to both sides of the equation:

x - 17,5 + 17,5 = 58 + 17,5

x = 75,5

So, the solution to the equation is:

x = 75,5
