5x+3x-7x+12-2x-13=9-6x+7+9x

Answer 1

Ответ:

x=-4,25

Пошаговое объяснение:

5x+3x-7x+12-2x-13=9-6x+7+9x

-x+12-2x-13=9-6x+7+9x

-x-1=9-6x+7+9x

-x-1=16+3x

Answer 2

To solve for the value of "x" in the given equation, let's first simplify and combine like terms on both sides of the equation:

5x + 3x - 7x + 12 - 2x - 13 = 9 - 6x + 7 + 9x

Now, simplify each side separately:

(5x + 3x - 7x - 2x) + (12 - 13) = (9 + 7) + (9x - 6x)

Combine the like terms:

-1x - 1 = 16 + 3x

Next, let's isolate the variables on one side and the constants on the other side. We can do this by adding 1x to both sides of the equation:

-1x + 1x - 1 = 16 + 3x + 1x

This simplifies to:

-1 = 16 + 4x

Now, subtract 16 from both sides to isolate the term with "x" on the right side:

-1 - 16 = 16 - 16 + 4x

-17 = 4x

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

x = -17/4

So, the solution for "x" is:

x = -17/4
