Answer 1

Ответ:

26+13х-17х=12х-7х-28

-4х-5х=-28-26

-9х=-54

х=6

Answer 2

Ответ:

13(2+x) -17x=12x-7(x+4)

Объяснение:

26+13x-17x= 12x-7x-28

26-4x=5x-28

-4x-5x= -28-26

-9x= -54

x = -54 ÷ -9

x=6

Ответ равен 6

Answer 3

To solve the equation 13(2+x) - 17x = 12x - 7(x+4), you'll need to simplify and isolate the variable x. Here's how you can do it step by step:

1. Distribute the numbers on both sides of the equation: 13 * 2 + 13 * x - 17x = 12x - 7 * x - 7 * 4

This simplifies to: 26 + 13x - 17x = 12x - 7x - 28

2. Combine like terms on each side of the equation: -4x - 26 = 5x - 28

3. Move all the terms with x to one side of the equation by adding 4x to both sides: -26 = 9x - 28

4. Add 28 to both sides of the equation to isolate the variable x: -26 + 28 = 9x

This simplifies to: 2 = 9x

5. Finally, divide both sides by 9 to solve for x: 2/9 = x

So, the solution to the equation is: x = 2/9
