Answer 2

Ответ:

х+2х-4х-11х=-4+1

3х-15х= -3

-12х= -3

х= -12:(-3)

х= 4

Answer 3

To solve the equation $(x+4)(2x-1) = x(3x+11)$, you can start by expanding both sides and then simplifying the equation. Here are the steps:

1. Expand both sides of the equation: $(x+4)(2x-1) = x(3x+11)$ becomes $2x^2 - x + 8x - 4 = 3x^2 + 11x$.

2. Combine like terms on both sides of the equation: $2x^2 + 7x - 4 = 3x^2 + 11x$.

3. Move all terms to one side of the equation to set it equal to zero: $2x^2 - 3x^2 + 7x - 11x - 4 = 0$.

4. Combine like terms again: $-x^2 - 4x - 4 = 0$.

5. Multiply the entire equation by -1 to make it easier to work with: $x^2 + 4x + 4 = 0$.

6. Factor the quadratic equation: $(x+2)(x+2) = 0$.

7. Solve for x: $x+2 = 0$.

8. Subtract 2 from both sides: $x = -2$.

So, the solution to the equation $(x+4)(2x-1) = x(3x+11)$ is $x = -2$.
