Question

9•(X-3) -4•(7+-3x) = 5-3x

Answer 1

Ответ: 2,5

Пошаговое объяснение:

9х-27-28+12х=5-3х

-27-28-5=-3х-12х-9х

24х=60

х=2,5

Если там минус , то так)

Answer 2

Let's solve the given equation step by step:

9•(X-3) - 4•(7+-3x) = 5-3x

Distribute the constants:

9X - 27 - 28 + 12x = 5 - 3x

Combine like terms on the left side:

21x - 55 = 5 - 3x

Now, let's isolate the variable terms on one side by adding 3x to both sides:

21x + 3x - 55 = 5

Combine the x terms:

24x - 55 = 5

Next, add 55 to both sides:

24x = 60

Finally, divide both sides by 24 to solve for x:

x = 60 / 24

x = 2.5

So, the solution to the equation is x = 2.5.
