Answer 1

1) 567-(а+67)=567-а-67=500-а 
2)(а+207)-7=а+200
3) в-27-34=в-61
4) 183-х-21=162-х
5) х-19+500=х+481
6) 454-(81+х)=373-х
7) х-271-19=х-290
8) 246-у-46=200-у
9) а-27+137=а+110
10) 500-х-140=360-х
а дальше подставлять если написано в дано, так как здесь дан только х больше ничего не могу добавить

Answer 2

1. To solve the equation 1.567 - (a + 67), we need to simplify the expression inside the parentheses first by adding a and 67. This gives us 1.567 - a - 67. Then, we can combine like terms by subtracting 67 from 1.567, which gives us 1.5. Finally, we can rewrite the equation as 1.5 - a. So, the solution is 1.5 - a.

2. To solve the equation (a + 207) - 7, we can simplify the expression inside the parentheses by adding a and 207. This gives us a + 207 - 7. Then, we can combine like terms by subtracting 7 from 207, which gives us 200. Finally, we can rewrite the equation as a + 200. So, the solution is a + 200.

3. To solve the equation v - 27 - 34, we can combine like terms by subtracting 27 from 34, which gives us 7. Finally, we can rewrite the equation as v - 7. So, the solution is v - 7.

4. To solve the equation 183 - x - 21, we can combine like terms by subtracting 21 from 183, which gives us 162. Finally, we can rewrite the equation as 162 - x. So, the solution is 162 - x.

5. To solve the equation x - 19 + 500, we can combine like terms by adding -19 and 500, which gives us 481. Finally, we can rewrite the equation as 481 + x. So, the solution is 481 + x.

6. To solve the equation 454 - (81 + x), we need to simplify the expression inside the parentheses first by adding 81 and x. This gives us 454 - 81 - x. Then, we can combine like terms by subtracting 81 from 454, which gives us 373. Finally, we can rewrite the equation as 373 - x. So, the solution is 373 - x.

7. To solve the equation x - 271 - 19, we can combine like terms by subtracting 271 and 19 from x, which gives us x - 290. So, the solution is x - 290.

8. To solve the equation 246 - y - 46, we can combine like terms by subtracting 46 from 246, which gives us 200. Finally, we can rewrite the equation as 200 - y. So, the solution is 200 - y.

9. To solve the equation a - 27 + 137, we can combine like terms by subtracting 27 from 137, which gives us 110. Finally, we can rewrite the equation as 110 + a. So, the solution is 110 + a.

10. To solve the equation 500 - x - 140, we can combine like terms by subtracting 140 from 500, which gives us 360. Finally, we can rewrite the equation as 360 - x. Given that x = 12.14, we can substitute this value into the equation to find the solution. So, the solution is 360 - 12.14.
