Question

A)625+(x-112)=921 б)191+(312+x)=625 в)239-(x+41)=168 г)513+(698-x)=725 Решите пожалуйста очент срочно!!

Answer 1

Ответ:

x + (525-112) = 921

x + 513 = 921

x = 921 - 513

x = 408

x + (191+312) = 625

x + 503 = 625

x = 625 - 503

x = 121

Answer 2

Ответ:

а) х=408

б) х=112

в) х=30

г) х=486

Пошаговое объяснение:

а) 625+х-112=921

513+х= 921

х= 921-513

х= 408

б)191+312+х=625

503+х = 625

х= 625- 503

х= 112

в) 239 -х -41 = 168

198- х = 168

-х = 198 -168

-х = -30

х= 30

г) 513+698-х=725

1211-х = 725

-х = 725 - 1211

-х = -486

х= 468

Answer 3

Solution to Equation A: 625 + (x - 112) = 921

To solve the equation A: 625 + (x - 112) = 921, we can follow these steps:

1. Simplify the equation by removing parentheses: 625 + x - 112 = 921

2. Combine like terms: x + 513 = 921

3. Move the constant term to the other side of the equation by subtracting 513 from both sides: x = 921 - 513

4. Perform the subtraction: x = 408

Therefore, the solution to equation A is x = 408.

Solution to Equation B: 191 + (312 + x) = 625

To solve the equation B: 191 + (312 + x) = 625, we can follow these steps:

1. Simplify the equation by removing parentheses: 191 + 312 + x = 625

2. Combine like terms: 503 + x = 625

3. Move the constant term to the other side of the equation by subtracting 503 from both sides: x = 625 - 503

4. Perform the subtraction: x = 122

Therefore, the solution to equation B is x = 122.

Solution to Equation C: 239 - (x + 41) = 168

To solve the equation C: 239 - (x + 41) = 168, we can follow these steps:

1. Simplify the equation by removing parentheses: 239 - x - 41 = 168

2. Combine like terms: 198 - x = 168

3. Move the constant term to the other side of the equation by subtracting 198 from both sides: -x = 168 - 198

4. Perform the subtraction: -x = -30

5. Multiply both sides of the equation by -1 to isolate x: x = 30

Therefore, the solution to equation C is x = 30.

Solution to Equation D: 513 + (698 - x) = 725

To solve the equation D: 513 + (698 - x) = 725, we can follow these steps:

1. Simplify the equation by removing parentheses: 513 + 698 - x = 725

2. Combine like terms: 1211 - x = 725
