Question

3/4х +2х+5=2 3/4х+4,1+0,9 помогите пж

Answer 1

3/4х +2х+5=2 и 3/4х+4,1+0,9

3/4х +2х - (3+8x)/4x= 4,1+0,9 - 5

(3-3+8x)/4x +2x = 5-5

8x+2x=0

10x=0

x=0

Answer 2

To solve this equation, we need to simplify both sides of the equation by combining like terms, and then isolate the variable (x) on one side of the equation. Here are the steps to follow:

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

   3/4x + 2x + 5 = 2 + 3/4x + 4.1 + 0.9

   Simplifying the right side, we get:

   3/4x + 2x + 5 = 6 + 3/4x

2. Subtract 3/4x from both sides of the equation to isolate the variable on one side:

   3/4x - 3/4x + 2x + 5 = 6 + 3/4x - 3/4x

   Simplifying, we get:

   2x + 5 = 6

3. Subtract 5 from both sides of the equation:

   2x + 5 - 5 = 6 - 5

   Simplifying, we get:

   2x = 1

4. Divide both sides of the equation by 2 to solve for x:

   2x/2 = 1/2

   Simplifying, we get:

   x = 1/2

Therefore, the solution to the equation is x = 1/2.
