Question

19-(10+1)=(..-10)-..=..-1=..

Answer 1

Ответ:

19-(10+1)=(19-10)-1=9-1=8

Answer 2

Let's break down the expression step by step:

1. 19 - (10 + 1) = 19 - 11 = 8

So, 19 minus the result of (10 + 1) is 8.

2. (x - 10) - y = 8

We'll use "x" and "y" as variables for the unknown values. Now, we need to find "x" and "y" such that this equation is satisfied.

3. x - 10 - y = 8

Now, we can simplify this equation further:

4. (x - y) - 10 = 8

5. x - y = 8 + 10

6. x - y = 18

So, the equation (x - 10) - y = 8 simplifies to x - y = 18.

7. x - 1 = 18

To isolate "x," we add 1 to both sides of the equation:

8. x = 18 + 1

9. x = 19

Now, we have found the value of "x" to be 19.

10. 19 - 10 = 9

To find the value of "y," we can substitute the value of "x" into the equation x - y = 18:

11. 19 - y = 18

Now, to isolate "y," we subtract 18 from both sides of the equation:

12. -y = 18 - 19

13. -y = -1

To solve for "y," we can multiply both sides of the equation by -1:

14. y = 1

So, the values of "x" and "y" that satisfy the equations are:

x = 19 y = 1

Therefore:

• (x - 10) - y = (19 - 10) - 1 = 9 - 1 = 8

So, the final result is 8.
