Answer 2

ОТВЕТ:

1,4=²⁵/₁₀₀

ОБЪЯСНЕНИЕ:

5х-(3+2х-2х²)=2х²-7х+11

5х+2х-2х²-2х²+7х=11-3

х=14÷10

х=1,4=²⁵/₁₀₀

Answer 3

To solve the equation 5x - (3 + 2x - 2x²) = 2x² - 7x + 11, follow these steps:

Step 1: Distribute the negative sign on the left side of the equation:

5x - 3 - 2x + 2x² = 2x² - 7x + 11

Step 2: Combine like terms on both sides of the equation:

(5x - 2x) + 2x² - 3 = 2x² - 7x + 11

This simplifies to:

3x + 2x² - 3 = 2x² - 7x + 11

Step 3: Subtract 2x² from both sides of the equation to eliminate the quadratic terms:

3x - 3 = -7x + 11

Step 4: Add 7x to both sides of the equation to isolate the variable terms on one side:

3x + 7x - 3 = 11

Combine like terms:

10x - 3 = 11

Step 5: Add 3 to both sides of the equation to isolate the term with x:

10x = 11 + 3 10x = 14

Step 6: Finally, divide both sides by 10 to solve for x:

x = 14 / 10 x = 7/5 or 1.4

So, the solution to the equation is x = 7/5 or x = 1.4.
