Question

2x+3=15 3-2x=24 2+3x=12

Answer 1

Ответ:

Пошаговое объяснение:

2x+3=15

2x = 15 - 3

2x = 12

x = 12 : 2

x = 6

3-2x=24

2x = 3 - 24

2x = -21

x = -21 : 2

x = -10,5

2+3x=12

3x = 12 - 2

3x = 10

x = 10 : 3

x = 3 1/3

Answer 2

To solve these equations, we'll solve them one by one. Let's begin:

1. 2x + 3 = 15

To isolate x, we'll subtract 3 from both sides:

2x + 3 - 3 = 15 - 3

This simplifies to:

2x = 12

Now, we'll divide both sides of the equation by 2 to solve for x:

(2x)/2 = 12/2

x = 6

So the solution to the first equation is x = 6.

2. 3 - 2x = 24

To isolate x, we'll subtract 3 from both sides:

3 - 2x - 3 = 24 - 3

This simplifies to:

-2x = 21

Now, we'll divide both sides of the equation by -2 to solve for x:

(-2x)/-2 = 21/-2

x = -10.5

So the solution to the second equation is x = -10.5.

3. 2 + 3x = 12

To isolate x, we'll subtract 2 from both sides:

2 + 3x - 2 = 12 - 2

This simplifies to:

3x = 10

Now, we'll divide both sides of the equation by 3 to solve for x:

(3x)/3 = 10/3

x = 10/3 or x = 3.33 (rounded to two decimal places)

So the solution to the third equation is x = 10/3 or x = 3.33 (rounded).
