Answer 1

Ответ:

Пошаговое объяснение:

6х-8-6х+15=28х-21+6х+8

7=34х-13

34х=20

х=20/34

х=10/17

Answer 2

To solve this equation, you'll need to simplify and isolate the variable x. Here are the steps to solve it:

1. Distribute the numbers outside the parentheses to the terms inside the parentheses on both sides of the equation.

On the left side: 2(3x - 4) - 3(2x - 5) becomes 6x - 8 - 6x + 15

On the right side: 7(4x - 3) + 2(3x + 4) becomes 28x - 21 + 6x + 8

Now, the equation looks like this:

(6x - 8 - 6x + 15) = (28x - 21 + 6x + 8)

2. Simplify each side of the equation by combining like terms:

On the left side, 6x and -6x will cancel each other out, and you'll be left with:

-8 + 15 = 7

On the right side, combine like terms:

28x + 6x = 34x -21 + 8 = -13

So the equation simplifies to:

7 = 34x - 13

3. Now, isolate the variable x. Add 13 to both sides of the equation:

7 + 13 = 34x - 13 + 13

20 = 34x

4. Finally, divide both sides by 34 to solve for x:

20/34 = 34x/34

10/17 = x

So, the solution to the equation is:

x = 10/17
