Question

- (4,1x + 2,5) - (2,3x + 3,9) = 1,6x 

Answer 1

- (4,1x + 2,5) - (2,3x + 3,9) = 1,6x
-4,1х-2,5 -2,3х-3,9-1,6х=0
-8х-6,4=0
-8х=6,4
х=6,4:(-8)
х=--0,8

Answer 2

- (4,1x + 2,5) - (2,3x + 3,9) = 1,6x  
-4,1х - 2,5 - 2,3х - 3,9 = 1,6х
-8х = 6,4
х= -0,8

Answer 3

To solve the equation:

(4 - 1x + 2.5) - (2.3x + 3.9) = 1.6x

Let's simplify the equation step by step:

First, distribute the negative sign in front of the parentheses:

4 - 1x + 2.5 - 2.3x - 3.9 = 1.6x

Combine like terms:

(4 + 2.5 - 3.9) - 1x - 2.3x = 1.6x

(6.5 - 3.9) - 3.3x = 1.6x

2.6 - 3.3x = 1.6x

Next, let's isolate the variable terms on one side by adding 3.3x to both sides:

2.6 - 3.3x + 3.3x = 1.6x + 3.3x

2.6 = 4.9x

Now, divide both sides of the equation by 4.9 to solve for x:

2.6 / 4.9 = x

x ≈ 0.5306

Therefore, the approximate value of x that satisfies the equation is x ≈ 0.5306.
