Question

82. 1) 321 + (x + 13) = 450; 3) 204 - (x +29) = 100;​

Answer 1

Ответ:

1: 106,3: 75

Пошаговое объяснение:

1) 450-321= x+13

2) x= 450- 321 450-321=129

3)x= 129-13

4)x= 106

5)321+(106+13)= 450

6) 450=450

7) ответ: х=106

1) 204-(х+29)= 100

2)204-100= х+29

3) х= 104- 29

4)х=75

5) 204-(75+29)=100

6) 100=100

7)ответ:х = 75

Answer 3

To solve the equations:

1. 321 + (x + 13) = 450
2. 204 - (x + 29) = 100

You can follow these steps:

Equation 1: 321 + (x + 13) = 450

First, simplify the equation by removing the parentheses: 321 + x + 13 = 450

Now, combine like terms: 334 + x = 450

Subtract 334 from both sides of the equation to isolate x: x = 450 - 334 x = 116

Equation 2: 204 - (x + 29) = 100

First, simplify the equation by removing the parentheses: 204 - x - 29 = 100

Now, combine like terms: 175 - x = 100

Subtract 175 from both sides of the equation to isolate x: -x = 100 - 175 -x = -75

To solve for x, multiply both sides by -1 to make x positive: x = 75

So, the solutions to the equations are:

1. x = 116
2. x = 75
