-2,92+8,2х-1,6+4,7х-2,9х=3,2

8,2х+4,7х-2,9х=3,2+2,92+1,6

10х=7,72

Х=о, 772

Answer 2

-2,92+8,2х-1,6+4,7х+2,9=3,2

8,2х+4,7х=2,92+1,6-2,9+3,2

12,9х=6,82

Answer 3

To solve the equation -(2.92 - 8.2x) - (1.6 - 4.7x + 2.9x) = 3.2, we need to combine like terms and isolate the variable x.

Let's start by simplifying the left-hand side of the equation:

Step 1: Distribute the negative sign in front of the parentheses: -(2.92 - 8.2x) - (1.6 - 4.7x + 2.9x) = -2.92 + 8.2x - 1.6 + 4.7x - 2.9x

Step 2: Combine like terms: = (8.2x + 4.7x - 2.9x) - (2.92 + 1.6) = 10x - 4.52

Now, the equation becomes: 10x - 4.52 = 3.2

Step 3: Isolate x by moving the constant term to the other side of the equation: 10x = 3.2 + 4.52 10x = 7.72

Step 4: Solve for x by dividing both sides by 10: x = 7.72 / 10 x = 0.772

So, the solution to the equation is x = 0.772.
