X - 14=42-19, 7*x=32+38, (42+18):x=5

Answer 1

Ответ:

Пошаговое объяснение:

x-14=42-19      7*x=32+38            (42+18):x=5

x-14=23           7*x=70                   42:x=18-5

x=23+14          x=70:7                    42:x=13

x=37,               x=10,                      x=42*13

                                                      x=4326

Answer 3

Let's solve each equation step by step:

1. X - 14 = 42 - 19

First, we simplify the right side of the equation:

X - 14 = 23

Next, we isolate X by adding 14 to both sides:

X = 23 + 14

X = 37

So the solution to the first equation is X = 37.

2. 7*X = 32 + 38

We simplify the right side of the equation:

7*X = 70

Next, we isolate X by dividing both sides by 7:

X = 70 / 7

X = 10

So the solution to the second equation is X = 10.

3. (42 + 18) / X = 5

We simplify the left side of the equation:

60 / X = 5

Next, we isolate X by multiplying both sides by X:

60 = 5 * X

Divide both sides by 5:

12 = X

So the solution to the third equation is X = 12.

To summarize the solutions:

1. X = 37
2. X = 10
3. X = 12
