на фото всё решение есть. х=0

Answer 2

Объяснение:

5x2+7x-2x-5x²+8=8

7x-2x+8=8

7x-2x=0

5x=0

х=0

Answer 3

To solve the given equation, let's simplify it step by step:

5x² + 7x - (2x + 5x² - 8) = 8

First, distribute the negative sign inside the parentheses:

5x² + 7x - 2x - 5x² + 8 = 8

Combine like terms:

(5x² - 5x²) + (7x - 2x) + 8 = 8

The x² terms cancel out:

0 + 5x + 8 = 8

Now, subtract 8 from both sides:

5x + 8 - 8 = 8 - 8

5x = 0

Finally, divide both sides by 5 to solve for x:

5x/5 = 0/5

x = 0

So, the solution to the equation is x = 0.
