Question

1)2х+17=22+3х 3)18+3х=х+14 5) 25-4х=12-5х​

Answer 1

Ответ:

Пошаговое объяснение:

1)

2х+17=22+3х

3x - 2x = 17 - 22

x = -5

3)

18+3х=х+14

3x - x = 14 - 18

2x = -4

x = -4 : 2

x = -2

5)

25-4х=12-5х​

5x - 4x = 12 - 25

x = -13

Answer 2

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

1. 2x + 17 = 22 + 3x

First, you want to get all the x terms on one side and the constants on the other side. You can do this by subtracting 3x from both sides of the equation:

2x - 3x + 17 = 22

Now, combine like terms:

-x + 17 = 22

Subtract 17 from both sides:

-x = 22 - 17

-x = 5

Now, to isolate x, multiply both sides by -1:

x = -5

So, the solution to this equation is x = -5.

3. 18 + 3x = x + 14

First, get the x terms on one side and the constants on the other side. You can do this by subtracting x from both sides:

18 + 2x = 14

Now, subtract 18 from both sides:

2x = 14 - 18

2x = -4

Now, to isolate x, divide both sides by 2:

x = -4 / 2

x = -2

So, the solution to this equation is x = -2.

5. 25 - 4x = 12 - 5x

First, get the x terms on one side and the constants on the other side. You can do this by adding 5x to both sides:

25 - 4x + 5x = 12

Now, combine like terms:

25 + x = 12

Subtract 25 from both sides:

x = 12 - 25

x = -13

So, the solution to this equation is x = -13.
