Question

(4,1x + 2,5) – (2,3x + 3,9) = 1,6x Решите уравнение

Answer 1

Ответ:

4,1х - 2,3х - 1,6х = 3,9 - 2,5

0,2х = 1,4

х = 7

Answer 2

To solve the equation, first, we need to combine like terms on both sides of the equation:

(4.1x + 2.5) - (2.3x + 3.9) = 1.6x

To do this, we'll remove the parentheses and then combine the x terms and constant terms separately:

Step 1: Remove the parentheses: 4.1x + 2.5 - 2.3x - 3.9 = 1.6x

Step 2: Combine the x terms: (4.1x - 2.3x) + (2.5 - 3.9) = 1.6x

Step 3: Perform the arithmetic on each side: 1.8x - 1.4 = 1.6x

Now, we want to isolate the variable x on one side of the equation. Let's move all the terms with x to the left side by subtracting 1.6x from both sides:

1.8x - 1.4 - 1.6x = 0

Now, combine the x terms again:

(1.8x - 1.6x) - 1.4 = 0

0.2x - 1.4 = 0

Next, add 1.4 to both sides to move the constant term to the right side:

0.2x = 1.4

Finally, isolate x by dividing both sides by 0.2:

x = 1.4 / 0.2

x = 7

So, the solution to the equation is x = 7.
