836-y=478 a-1027=4939 a-712=1342 10837+a=18400 (x-87)-27=36 87-(41+y) =22

Answer 1

Ответ:

836-у=478

у=836-478

у=358

836-358=478

478=478

а-1027=4939

а=4939+1027

а=5966

5966-1027=4939

4939=4939

а-712=1342

а=1342+712

а=2059

2059-712=1342

1342=1342

10837+а=18400

а=18400-10837

а=7563

10837+7563=18400

18400=18400

(х-87)-27=36

(х-87)=36+27

(х-87)=63

х=87+63

х=150

(150-87)-27=36

36=36

87-(41+у)=22

(41+у)=87-22

(41+у)=65

у=65-41

у=24

87-(41+24)=22

22=22

Answer 2

To solve these equations, let's go through them one by one:

1. 836 - y = 478 First, isolate the variable "y" by moving -y to the other side of the equation and simplify.

   836 - y - y = 478 - y 836 - 478 = y

   y = 358

2. a - 1027 = 4939 Isolate variable "a" by moving -1027 to the other side of the equation and simplify.

   a = 4939 + 1027 a = 5966

3. a - 712 = 1342 Isolate variable "a" by moving -712 to the other side of the equation and simplify.

   a = 1342 + 712 a = 2054

4. 10837 + a = 18400 Isolate variable "a" by moving 10837 to the other side of the equation and simplify.

   a = 18400 - 10837 a = 7563

5. (x - 87) - 27 = 36 First, add 27 to both sides of the equation to isolate the expression (x - 87).

   (x - 87) - 27 + 27 = 36 + 27 (x - 87) = 63

   Now, add 87 to both sides to solve for "x."

   x - 87 + 87 = 63 + 87 x = 150

6. 87 - (41 + y) = 22 First, simplify the expression inside the parentheses.

   87 - (41 + y) = 22

   Now, subtract 87 from both sides.

   • (41 + y) = 22 - 87
   • (41 + y) = -65

   To isolate the negative sign, multiply both sides by -1.

   41 + y = 65

   Finally, subtract 41 from both sides to solve for "y."

   y = 65 - 41 y = 24

So, the solutions to the equations are as follows:

1. y = 358
2. a = 5966
3. a = 2054
4. a = 7563
5. x = 150
6. y = 24
