Question

1,5x-4(x+2,5)=5,6+2,7x

Answer 1

Ответ:

-3

Пошаговое объяснение:

1,5x - 4(x+2.5) = 5.6 + 2.7x

1.5x - 4x - 10 = 5.6 + 2.7x

-5.2x = 15.6

x = -3

Answer 2

1,5х-4х-2,7х=10+5,6
-5,2х=15,6
х=15,6:(-5,2)
х=-3

Answer 3

Let's solve the given equation step by step.

1,5x - 4(x + 2,5) = 5,6 + 2,7x

First, distribute the -4 to the terms inside the parentheses:

1,5x - 4x - 10 = 5,6 + 2,7x

Combine like terms on both sides of the equation:

(1,5x - 4x) - 10 = 5,6 + 2,7x

-2.5x - 10 = 5,6 + 2,7x

Next, let's isolate the variable terms on one side and the constant terms on the other side. We'll start by moving the 2,7x term to the left side by subtracting 2,7x from both sides:

-2.5x - 2,7x - 10 = 5,6

Now, combine the x terms on the left side:

-5.2x - 10 = 5,6

Next, we'll move the constant term (-10) to the right side by adding 10 to both sides:

-5.2x = 5,6 + 10

Simplifying the right side:

-5.2x = 15.6

To solve for x, divide both sides of the equation by -5.2:

x = 15.6 / -5.2

Simplifying the right side:

x = -3

So the solution to the equation is x = -3.
