Question

(30+(40+(50-(x-5)))=20

Answer 1

(40+(50-(x-5)))=-10
(50-(x-5))=-50
-(x-5)=-100
-x=-95
x=95
вообщем я проверила, но ответы почему-то не сходятся а вы уверены то что там = 20, а не 30?
просто если посчитать всё с х=95 должно получится 30

Answer 2

Ответ х=105.

Answer 3

To solve the equation (30 + (40 + (50 - (x - 5)))) = 20, you can follow these steps:

1. Start by simplifying the innermost parentheses first:

   30 + (40 + (50 - (x - 5)))

   = 30 + (40 + (50 - x + 5))

2. Continue simplifying:

   = 30 + (40 + 55 - x)

3. Further simplify the parentheses:

   = 30 + (95 - x)

4. Now, simplify the remaining parentheses:

   = 30 + 95 - x

5. Combine like terms:

   = 125 - x

6. Now, set the equation equal to 20 and solve for x:

   125 - x = 20

7. To isolate x, subtract 125 from both sides of the equation:

   -x = 20 - 125

   -x = -105

8. Finally, multiply both sides by -1 to solve for x:

   x = 105

So, the solution to the equation (30 + (40 + (50 - (x - 5)))) = 20 is x = 105.
