Question

Решите уравнение 7 класс 8х(3+2х)-(4х+3)(4х-3)=9х-6

Answer 1

Раскрываем скобки:
24х + 16х(в квадрате) - 16х(в квадрате) + 12х - 12х + 9 = 9х - 6
9 + 6 = - 24х + 9х
15 = - 15х
х = - 1

Answer 2

I can help you solve this equation. First, let's expand the brackets and simplify the terms:

$$8x(3+2x)-(4x+3)(4x-3)=9x-6$$ $$24x+16x^2-16x^2+12x-12x+9=9x-6$$ $$24x-9=9x-6$$

Next, let's move all the x terms to one side and the constants to the other:

$$24x-9x=9-6$$ $$15x=3$$

Finally, let's divide both sides by 15 to get the value of x:

$$x=\frac{3}{15}$$ $$x=\frac{1}{5}$$

Therefore, the solution is $$x=\frac{1}{5}$$. I hope this helps.Ответь+подробно.+Решите+уравнение+7+класс+8х(3+2х)-(4х+3)(4х-3)=9х-6
