Question

3x(x-2)-x(3x+3)=18-4x

Answer 1

Ответ:

х= -3 3/5 или -3,6

Объяснение:

3х(х-2)-х(3х+3)=18-4х

Раскроем скобки

3x^2 - 6x -3x^2 -3x=18-4x

Сократим противоположные слагаемые и приведем подобные

-9х =18-4х

-9х+4х=18

-5х= 18

х= -3 3/5 или -3,6

Answer 2

Відповідь:

$x=-3\frac{3}{5}$

Пояснення:

$3x^{2} - 6x - 3x^{2}-3x=18-4x\\3x^{2}-3x^{2}-6x-3x+4x=18\\-5x=18\\x=-\frac{18}{5} \\x=-3\frac{3}{5}$

Answer 3

Let's solve the equation step by step:

3x(x-2) - x(3x+3) = 18 - 4x

First, simplify both sides of the equation by expanding the expressions:

3x^2 - 6x - 3x^2 - 3x = 18 - 4x

Now, combine like terms on both sides:

(3x^2 - 3x^2) + (-6x - 3x + 4x) = 18 - 4x

Simplify further:

0 - 5x = 18 - 4x

Now, isolate the variable x by adding 4x to both sides of the equation:

-5x + 4x = 18 - 4x + 4x

This simplifies to:

-x = 18

Finally, divide both sides by -1 to solve for x:

x = -18

So, the solution to the equation is x = -18.
