Question

1) 321 + (x + 13) = 450; 3) 204 – (x + 29) = 100;1) (x – 23) · 14 = 56;3) 205 : (y – 27) = 41;​

Answer 1

Пошаговое объяснение:

1)

321 + (x + 13) = 450

321 + x + 13 = 450

334 + x = 450

x = 450 - 334

x = 116

3)

204 – (x + 29) = 100

204 - x + 29 = 100

175 - x =100

-x = 100 - 175

-x = -75

x = 75

1)

(x – 23) · 14 = 56

14x - 322 = 56

14x= 56 + 322

14x=378

x=27

Answer 2

Ответ:

1)

321 + (x + 13) = 450

321 + x + 13 = 450

334 + x = 450

x = 450 - 334

x = 116

3)

204 – (x + 29) = 100

204 - x + 29 = 100

175 - x =100

-x = 100 - 175

-x = -75

x = 75

1)

(x – 23) · 14 = 56

14x - 322 = 56

14x= 56 + 322

14x=378

x=27

Answer 3

Let's solve each of these equations step by step:

1. 321 + (x + 13) = 450

First, simplify the equation by removing the parentheses:

321 + x + 13 = 450

Now, combine like terms on the left side of the equation:

334 + x = 450

Next, isolate x by subtracting 334 from both sides of the equation:

x = 450 - 334 x = 116

So, the solution to the first equation is x = 116.

2. 204 - (x + 29) = 100

First, simplify the equation by removing the parentheses:

204 - x - 29 = 100

Now, combine like terms on the left side of the equation:

175 - x = 100

Next, isolate x by subtracting 175 from both sides of the equation:

-x = 100 - 175 -x = -75

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

x = 75

So, the solution to the second equation is x = 75.

3. (x - 23) * 14 = 56

First, divide both sides by 14 to isolate the term (x - 23):

(x - 23) * 14 / 14 = 56 / 14

Simplify:

x - 23 = 4

Now, isolate x by adding 23 to both sides of the equation:

x = 4 + 23 x = 27

So, the solution to the third equation is x = 27.

4. 205 / (y - 27) = 41

First, multiply both sides of the equation by (y - 27) to isolate it on the left side:

205 = 41 * (y - 27)

Now, divide both sides by 41 to solve for (y - 27):

(y - 27) = 205 / 41

Simplify:

(y - 27) = 5

Now, isolate y by adding 27 to both sides of the equation:

y = 5 + 27 y = 32

So, the solution to the fourth equation is y = 32.
