Question

2,1x+2,3x+2,5x=6x+1,926

Answer 1

2,1х+2,3х+2,5х-6х= 1.926.
0,9х=1,926.
х=1,926:0,9
х=2.14.

Answer 2

6,9 х = 6х + 1,926
6,9 х - 6х = 1,926
0,9х = 1,926 
х = 1,926 : 0,9
х = 2,14
Проверка:
6,9 * 2,14 = 2,14* 6 + 1,926
14,766 = 14, 766

Answer 3

To solve the equation 2.1x + 2.3x + 2.5x = 6x + 1.926, you can start by combining like terms on both sides of the equation:

2.1x + 2.3x + 2.5x = 6x + 1.926

Combine the x terms on the left side:

(2.1x + 2.3x + 2.5x) = (2.1 + 2.3 + 2.5)x

Now, add the coefficients of x:

(7.9x) = (7.9)x

The equation simplifies to:

7.9x = 7.9x

At this point, you can see that both sides of the equation are equal, which means that the equation is an identity. In other words, for any value of x, the equation will be true. Therefore, the solution to this equation is all real numbers, or in interval notation, (-∞, ∞).

Answer 4

To solve this equation for x, you can start by simplifying and combining like terms on both sides of the equation:

2.1x + 2.3x + 2.5x = 6x + 1.926

Now, add the x terms on the left side:

(2.1x + 2.3x + 2.5x) = 7.9x

So, the equation becomes:

7.9x = 6x + 1.926

Next, you can move the 6x from the right side to the left side by subtracting 6x from both sides of the equation:

7.9x - 6x = 6x - 6x + 1.926

This simplifies to:

1.9x = 1.926

Now, to solve for x, divide both sides by 1.9:

(1.9x)/1.9 = 1.926/1.9

x = 1.01368421053 (rounded to several decimal places)

So, the solution to the equation is approximately:

x ≈ 1.0137

Answer 5

To solve the equation for x, you'll need to simplify and isolate x on one side of the equation. Let's break it down step by step:

2.1x + 2.3x + 2.5x = 6x + 1.926

First, combine like terms on both sides of the equation:

(2.1x + 2.3x + 2.5x) - 6x = 1.926

Now, add up the x terms on the left side:

(2.1x + 2.3x + 2.5x - 6x) = 1.926

Combine the x terms:

(2.1x + 2.3x + 2.5x - 6x) = 1.926

(7.9x - 6x) = 1.926

Now, simplify the left side:

1.9x = 1.926

To isolate x, divide both sides by 1.9:

(1.9x) / 1.9 = 1.926 / 1.9

x = 1.01473684

So, the solution to the equation is approximately x = 1.0147 (rounded to four decimal places).
