Пошаговое объяснение:

2x+17=22+3x

2х-3х=22-17

-х=5

х=-5

18+3x=x+14

3х-х=14-18

2х=-4

х=-4:2

х=-2

25-4x=12-5x

5х-4х=12-25

х=-13

Answer 2

To solve each of these equations, we'll isolate the variable (x) on one side of the equation. Let's solve each one step by step:

1. 2x + 17 = 22 + 3x

To isolate x, let's move all the terms containing x to one side and constants to the other side.

Subtract 2x from both sides: 2x - 2x + 17 = 22 - 2x + 3x

Simplify: 17 = 22 + x

Subtract 22 from both sides: 17 - 22 = x

Simplify: x = -5

So the solution for the first equation is x = -5.

2. 18 + 3x = x + 14

To isolate x, let's move all the terms containing x to one side and constants to the other side.

Subtract x from both sides: 18 + 3x - x = x - x + 14

Simplify: 18 + 2x = 14

Subtract 18 from both sides: 18 - 18 + 2x = 14 - 18

Simplify: 2x = -4

Now, divide by 2 to solve for x: x = -4 / 2

Simplify: x = -2

So the solution for the second equation is x = -2.

3. 25 - 4x = 12 - 5x

To isolate x, let's move all the terms containing x to one side and constants to the other side.

Add 5x to both sides: 25 - 4x + 5x = 12 - 5x + 5x

Simplify: 25 + x = 12

Subtract 25 from both sides: 25 - 25 + x = 12 - 25

Simplify: x = -13

So the solution for the third equation is x = -13.

To summarize:

1. x = -5
2. x = -2
3. x = -13
