Question

20х – (3х +2,6) = 3(0,8 + 3х)

Answer 1

Ответ:

20x-(3x+2,6)=3(0,8+3x)

20x-3x-2,6=2,4+9x

20x-3x-9x=2,4+2,6

8x=5

x=5/8

Answer 3

To solve the equation 20x - (3x + 2.6) = 3(0.8 + 3x), follow these steps:

1. Distribute the 3 on the right side of the equation:

   20x - (3x + 2.6) = 2.4 + 9x

2. Now, let's simplify the equation by combining like terms on both sides:

   20x - 3x - 2.6 = 2.4 + 9x

3. Combine like terms on each side of the equation:

   17x - 2.6 = 2.4 + 9x

4. To isolate x on one side, subtract 9x from both sides of the equation:

   17x - 9x - 2.6 = 2.4

5. Simplify the left side by subtracting 9x from 17x:

   8x - 2.6 = 2.4

6. Add 2.6 to both sides to isolate the term with x:

   8x - 2.6 + 2.6 = 2.4 + 2.6

7. Simplify:

   8x = 5

8. Finally, divide both sides by 8 to solve for x:

   (8x) / 8 = 5 / 8

   x = 5/8

So, the solution to the equation is:

x = 5/8
